♪ emily: i am emily chang and this is the best of "bloomberg west" where we bring you the top news in tech. coming up, the iphone maker coughs up $18 billion. is europe putting tech giants a notice? plus, shares jumped off a conversation with ed williams. we will bring you the interview with the twitter cofounder.

it is go time for commercial drones. we will discuss the regulations. the first, to the week for lead -- european regulators slammed apple with a $14.5 billion tax bill, the largest tax penalty in the eu's crackdown on so-called sweetheart deals. these are arrangements which a company moves profits to where they're taxed advantageously. in this case, ireland. its corporate tax rate is the lowest in western europe and it is attracting more than 700 u.s. companies to set up shop, including google and facebook. apple employs 6000 people in ireland. in this week's ruling, the eu commissioner said that ireland allowed apple to pay an effective tax rate that was down to .5%, which gave apple and unfair vantage. here she is in an interview with bloomberg tuesday. >> the tax rate in ireland is

12.5%. obviously, most companies, they pay corporate tax rate in ireland. they have to look at some companies, in this case, apple, only pay a tiny, tiny fraction of the tax that they pay. that is not fair competition. it is not a level playing field. emily: we also spoke to the irish finance minister and we will bring you his comments in a moment. take a listen with bloomberg litigation specialist matt larson and alex webb on apple's response. >> apple's defense is they have been an island for a long time. this agreement has been in place since 1991. it was always legal. they never lost any legal loopholes. the argument with ireland was such that they were completely

on board with the legislation. from also have a letter tim cook to users. i believe it includes steve jobs. >> yes, apple, as ever, they always talk about their customers. not journalists. who is writing the stories? of course, journals. emily: what are the next steps apple in a legal battle? >> apple and ireland will appeal this decision to the european general court in luxembourg. it is the same court hearing the appeals in the starbucks, netherlands investigation and the fiat chrysler case. both are significantly smaller but could give some indication in how the appeals court may take the decision. this whole process is going to take, ballpark, two years to determine. after that, there are for the -- further opportunities to

appeal to higher courts in europe. it will be a while until we get a final decision. emily: alex, leading up to this point, the u.s. has been stepping up its defense of apple calling the eu a super unnatural tax authority, indicating the are overstepping their bounds. what do we hear from yet if it's -- the united states government today? >> they are not happy. you have to be careful calling them a defense of apple. they are interested in is insuring the tax is paid in the u.s. every dollar that apple pays in tax overseas is deducted from the taxing me have to pay in the u.s. should they ever repay trade their funds. -- repatriate their funds. $14 million going to ireland, that is $14.5 billion not going to the irs. emily: we mention that apple is fighting this ruling and ireland is fighting this as well. why wouldn't ireland want to collect from the richest company in the world?

they point out the opposition party would like to see just that. >> why don't you just accept the money and shut up? 13 billion euros plus interest is a lot of money. >> because as a minister of finance, i have a responsibility of advising the government on these matters. this is a government that a rescued ireland from the verge of bankruptcy from 2011 on. it is fundamental to our economic policies, and we stand by our economic policies, and we are going to protect our economic policies. we're not going to get into a situation of short-term gain for long-term damage of the economy. >> standing his ground there, alex. what kind of long-term damage by we talking about? what have we heard from other tech companies? >> this is, as we heard yesterday, people were saying on a scale from one to 10, 10 being extremely damaging, a two to

three. ireland has thousands of people employed by tech companies -- start atis those jobs risk. it seems to be the obvious place where americans would go if they go to europe. the thing is also from the flipside, if you are any other country in europe, ireland is 80 billion euros in debt. so, this $14.5 billion will go toward paying this off. if you are a german citizen you are thinking why should i subsidize apple to have 5.5 million jobs in ireland? emily: i know you have been going in the weeds of it on this. looking at the tax records that other companies have, do any of them have similar arrangements? >> a lot of companies make use of ireland. we consider it the austin, texas of europe. ireland has developed favorable tax laws, specifically relating to transfer pricing.

what this whole apple investigation to go -- took a look at. as a result, you got a lot of companies that have organizations, subsidiaries set up in ireland that have these transfer pricing arrangements in place. you also have a big content -- conclusion life science pharmaceutical companies. that has significant operations in ireland, both because it is a good place to be, there are favorable tax laws and favorable treatment and how their tax system treats these transfer price agreements. it is a little bit of a warning shot from the european commission and it may encourage some companies to take a second look at whether they have negotiated too sweet of a tax deal, or even take a look at corporate structures and how the overall multinationals up is working for them. emily: our conversation with bloomberg intelligence analyst matt larson from washington and bloomberg news reporter alex webb covers apple.

coming up, our market moving conversation with the ceo of medium and cofounder of twitter. hospitals are prescribing patient's a healthy dose of virtual reality. we will discuss why vr is becoming a more affordable option for doctors. this is bloomberg. ♪

emily: evan williams has played a role on how users express themselves online, from founding blogger in 1999, he went on to start podcasting, and from then, a little side project called twitter was born. he became ceo of twitter and remains on the board of directors. he was not done. in 2012, he started medium for a way to publish. he joined us this week for a

lengthy interview. take a listen. >> medium is a way to write stories and ideas, and is meant to be open for anyone to find her audience. it is an update on blogging and social media, but it is focused on things that can be longer. everyone from the president has published on it, to individuals who just have personal stories to tell. emily: president obama, bono, hillary clinton? what do you see is the balance between amateurs, influencers, and publishers? >> we think the mix is really important and makes a conversation better. the entire point of medium,

unlike a stand-alone website, if you publish on medium, you are in the mix. it is -- your ideas bounce around with other people and you can respond. people can find you. one of our mottos is great ideas can come from anywhere. many professional journalists and creators and writers creating all the time, but especially when it comes to writing, there are tons of individuals that have unique perspectives and ideas and the ability to articulate them. we offer a place to do that do -- to do that and find your audience. the mix is what makes it work. it is where a business leader can respond, can write something and their customer can respond to them, or vice versa. because there is that diversity of voices, you get much more insight. emily: it is simple, elegant. where are your monetization? how do you maintain that experience and make money at the same time? >> we are working on growing the monetization piece right now. we just started it in the spring

after working on the platform for a couple of years and making it work for a couple of individuals. we are working on enabling professionals, means getting them paid. we have advertising is part of the product now where brands are publishing on medium and working on the publishing side. some publishers are implementing our subscription program as well, so you can create a membership program for your content. that is looking good, but it's in its early stages. emily: hillary clinton used medium to disclose her vp pick. mitt romney explained why he is not running for president. how does that come about? do you have a team of people trying to get hillary to post on medium? what is the play-by-play? >> we have an outreach team in d.c.

that is a white glove service team. they help get the ball rolling. it has taking on its own momentum. you can see medium has become the default if whether you are in d.c. or active in that world, or has something of substance to say, medium has become the default for that. all the major political campaigns, lots of professional -- major campaigns are on there, save one, so it has gotten this momentum. people from that world read it. emily: it is interesting because these are things that would be published as often as in traditional newspapers. one person who has not published on medium is donald trump. any effort to get him? >> we her happily open -- we are happily open to what he has to say. we are happy to add him to the mix. emily: he has taken find

advantage of twitter. him [laughter] he seems to express himself in 140 characters. what is it like watching trump takeoff on twitter? >> the same as everybody else, i guess. a mixture of bewilderment and some fear. it has been fascinating, especially the most recent revelation that his tweets -- you can distinguish his tweets from his staff by looking at the source. years ago when we built in that ability to see the source, we did not picture that particular use case for that, but kind of glad that is there. withprovocative article, the title, silicon valley created donald trump. do you think silicon valley created donald trump, or twitter created donald trump?

without twitter, donald trump would not be where he is? >> i would hate for us to take the credit or the blame for that. i think it is a result largely of our media ecosystem now that has tremendously good and bad things. so, that's -- when i started working on the internet, i was very excited that anyone could put their voice out there, and i really thought, the world is going to be smarter, wiser, more intelligent when the truth is out there unfettered. really, the reason we are still working in this area, i realized it is not as simple as that. the tremendous amount of noise has not made us smarter in many ways, it has made us dumber. they're ours -- there are so much we have to do to stay on top of this free flow of information to take it and of the society. we have a lot of work to do. emily: you have had plenty ceos saying the are against trump. do you think he would be good or bad for innovation?

>> i am firmly against trump. emily: how do you balance your personal and political views? we saw this issue, up with facebook and they're trending topics session where they were accused of the prioritizing conservative stories, which they fervently denied. it's interesting -- >> i will also say, i am not firmly against all republicans. what i am proud of is on twitter and medium, we built platforms that are neutral and work hard given equal size. we have -- many senators, many congresspeople. we have an even mix on both sides. on our outreach team, we

employed in equal number of people who reach out to the right and left. there is nothing in our system and biases one side over the other. that has created a very healthy exchange. i read and recommend viewpoints from both sides. because they are on the same platform, again, people are more open to them. emily: we will continue our conversation ahead, asking the twitter cofounder about potential twitter m&a. that is next. this is bloomberg.

emily: back to our conversation with twitter cofounder and medium ceo evan williams. medium has become a platform where influencers of all kind post in a longer form. president obama, bill gates, bono, ford, hbo, just a few examples of people and companies who have used medium to share their thoughts with the world. there was a heated debate about inthere was a heated debate about freedom of the press and where it stops. i asked evan williams in part

two of our conversation. evan: it is a little bit scary for the press, especially if a -- an unknown source of money is fighting you. while i wasn't a fan of everything gawker did, freedom of the press is critical. gawker should prevail in the appeal. it would be a bad thing if random media sites can be taken out for people who don't like what they say. emily: it is an important question that you deal with the scenes a lot -- behind the scenes a lot -- what is free speech and what counts as fair? what is going to far? -- what is going too far? when you started blogger, there was online harassment. it seems like nothing has changed. evan: it has gotten worse for sure.

the early days of the internet, it was a little better and we felt like there is a big club and if you are there, you are welcome. to use the metaphor, we had dinner parties with our front door open. if you stopped by, everyone was glad to see you. so much of the internet has evolved with that same default framework. the idea that anyone can join any conversation is not something we expect in the real world. because so many wonderful things come from that online, there is a lot of desire to hold onto that ability, and yet, it causes so much problems when you open it up to the masses. emily: why is it so hard to quiet the trolls? evan: because the line is always fuzzy. when you dig into these issues, it seems much easier from the outside when you look at the details. there is a lot of stuff, a lot of the rhetoric would give you the impression that twitter and other services don't do

anything. in there is a huge team focused on this issue and delete stuff all the time. where it is tricky is where the lines get blurry, and if you anything. have a philosophy of we want to defend free speech, and we want to allow people the principle of free speech, you have to. -- you have to defend speech even if you don't agree with it. even though it is not a legal agreement because twitter is a private entity, as are all of these other services. it is a value that we hold that people should be able to get out. even if they are unpopular, and therefore, there is a judgment call all the time. the policies are evolving. the tools are evolving. emily: do you think twitter should have taken this down -- taken this on sooner? evan; this was the knowledge

a couple of years ago. and myself, even from the earliest days, we would have thought about a different architecture for the service had we had known how the sitter of an issue this would get. it has gotten worse in terms of the vitriol and the level, and the severity of the attack some suffered. a lot of the architecture of the service of what allows really great things, does allow the bad things. i met with the team recently working on this. there is a bunch of smart people who are going to be improving this. emily: you are cofounder of twitter one of the biggest shareholders of twitter, and the biggest champion of twitter. this is a company that had a market cap of $25 billion and now is at $13 billion. could it get back to those heights? evan: i cannot make any does real statements being a board number of twitter.

i think very abstractly speaking, it is a large service and a valuable service. there will be -- the thing that twitter provides to the world is incredibly valuable. it can be more valuable. it is a matter of innovation and development. there is not an asset like twitter in the world in terms of the mix of individuals and world leaders, and entertainers, and all the information created on a daily basis. there is so much more that can come out of that. i would say, you know, i am an optimist in general. emily: what is your faith in jack? evan: i fully support jack. emily: i know you can only go so far. we see a lot of m&a. do you see twitter remaining an independent company?

evan: no comment on that. we are in a strong position right now, i think. as a board member, we got to consider the right options. emily: the last twitter sized medium question -- medium is a complement to twitter, but it is almost the opposite of twitter. do you see them as potentially opposites in a way? evan: in a way. part of my reason for working on medium is in the few years while an twitter grew and facebook evolved and instagram and all of the social media platforms, it him him him him took an increasing amount of attention and energy and innovation of our technology development. they still all talked about nonsocial media. articles, text, journalism was

still incredibly important. it had not evolved as much. at least, online publishing had not evolved as much over those years. that is why they are incredibly complementary, even though they are different. twitter is more of a distribution vehicle with more substantive content then it is somewhere where you expand on ideas, or offer more complex arguments or stories. twitter and medium are complementary. emily: that was evan williams, twitter cofounder and medium ceo. coming up, some call it a silent revolution. could the adoption of digital health care disrupt the economy? we talked to a veteran health care investor next. if you like bloomberg news,

♪ emily: welcome back to the best of "bloomberg west" it is time now for series a. this week, we spoke to stephen kraus who heads up the firm's health care investing. a blood testing startup drew application for a diagnostic blood test for the zika virus after regulators found problem with the way they were gathering patient data. this coming after u.s. regulators sanctioned theranos. we asked his thoughts on the startup. take a listen. you have been investing in the space longer than newer investors.

i wonder if you seen anything like this? stephen: it is amazing. for someone who cares deeply about putting products and services in the hands of patients and doctors, it is pretty maddening. anyone who is serious as a health care investor and entrepreneur -- enough is enough. the company had to pull back test results. they have had partners leave them. anyone who is serious as a another zika result proves they did not operate the clinical trial well. it is frustrating. it overshadows a lot of the great work that is happening in health care. emily: did she pitch to your? stephen: she did not and if you talk to most health care investors, she did not pitch to anyone who had health care experience. it is a complex industry where you think you would want folks who have health care experience. i hope we can talk about a lot of other great promising companies. it is very frustrating and i think it proves if you try to

put valuations ahead of patients you're going to get , burned. emily: where do you see potential? there are a lot of newer investors getting into the space. you have been doing this a long time. stephen: it is a great time in health care. this is an industry for too long has been pretty archaic and behind other modern industries in terms of technology. i think we are in the 1990's of enterprise software in health care. only five years ago, 50% of doctors did not use software to capture your clinical information. that is shocking. emily: pretty sure my doctor still right on a notepad. stephen: that is a problem and that is changing. five years of health care and nowhere. if you want to manage a population's health, and you don't have that information, you cannot really change health care for the better or lower costs or improve quality. that is where we are sitting

today. five years later, you 500% of doctors using digital health records. now you can do things happening in other industries like complex data analytics. that can really improve the quality of care and the cost of care. emily: where do you see the most disruption? stephen: i think it is the analytics layer. you have companies like flat iron catalyst health that have raised attractive rounds. i think consumerization of health. there are many things that are happening in the healthcare ecosystem. you see the rise of individual exchanges and you see individuals having to pay thousands of dollars or more. 10 years ago only 10% of patients had to pay 10% of deductibles. consumerism in health care is an interesting thing in terms of place to invest in terms of apps and software. emily: apple bought a company in this area.

they have barely scratched the surface. do you think they can become a big player here? stephen: i think apple is making the moves. i think glimpse is really interesting. this concept of a personal health record. we all should want to own our health data and want to know about our health data. the idea of a personal health record has been around for a decade and hasn't taken form. glimpse is a personal health record and apple has the interface and the dominant market share with their devices maybe the integration of the personal health record can make it a reality for patients and get them involved. emily: how do you see the exit environment for biotech and health tech companies? in comparison to enterprise tech. apple has made an acquisition. ibm has been very inquisitive. what is the environment like right now? they require a lot of money and a lot of capital. stephen: they require a lot of capital.

when you think about biotech and health care i.t., they are very different. they look a lot like consumer technology companies. there are innovative technologies that gain scale in the marketplace and then companies like ibm and google will come in and acquire them. they have to have exposure to the largest sector of our economy. it is an economic exposure play. the large software companies will make those acquisitions. $40 billion has been spent your today in health care i.t.. pharmaceuticals, it is different. they are in the earlier stage. they are moonshots. they have outsourced research and development to biotech companies so they are making those acquisitions well. emily: the company you invested in, it was so fascinating and exemplifies what you do. they went public very fast. they are focusing on reproductive technology where

there has not been a lot of -- innovation. talk to me about making a bet on this company where there is so potential, but a lot is unproven. stephen: having a child is one of the most important things people can do. humans can do. ova-science is trying to help couples facing infertility, give them technology that gives them hope to have a child. the technology was finding that reverse scientific dogma, that women are born with a certain number of eggs, and that depletes overtime. it turns out that that may not be true. the ova science founder found that women have stem cell like properties in the ovarian pool. the eggs can refurbish and you can harnish that technology to help women become fertile and have a child. i cannot imagine of a greater company to invest in. the founder is awesome. it is a perfect combination of what we do at venture capital. we invest in a huge dream that changes peoples'lives. how would you not want to invest

that as a public or private investor? if they are right, it is a huge multimillion dollar opportunity. emily: what is your take on this mylan epipen? controversy/outrage. stephen: outrage. an unfortunate time with kids going back to school. the company has had to react. their stock price has taken a hit. it's a good thing when the markets have morals to them, too. athink it is important for company like mylan is simply marketing a generic. greateruld have much pricing power. clinton.ump versus who is better?

, clinton will provide stability in the markets. that is important because you are making long-term bets in public policy involvement. emily: last question, stem centrex was a recent biotech deal that had huge acquisition for $10.2 billion. is this a deal that traditional vc's missed. how did that happen and how do you make sure we get the next one? stephen: we always make sure we can get the next one. emily: it was not just you. stephen: it is an interesting area of stem cell technology. it could be a moonshot. the acquisition could be zero. we miss some and we get some. emily: so fascinating. it could be zero yet they are paying $10.2 billion for it? stephen: if it works, it could also be, for instance mylan, , which is not a very innovative produces -- these are

highly profitable companies when you develop a drug and they work. they are multibillion-dollar franchises. emily: coming up, cleared for takeoff, the new regulations that could get commercial drones in the air faster. ♪

♪ emily: thousands of would-be drone pilots are racing to get licensed under new regulations that went into effect this week. it removes having getting special privileges, a process that took months. more than 3000 people have signed up to take the test so far and the faa is estimating the number of drone operators will exceed the nation's 171,000 private pilots in a year. we caught up with a company that provides on-demand drone insurance. >> before you could fly a drone commercially, but you had to get a special exemption and it took quite a while. they streamlined it. you had to be a licensed pilot. now you can do it as a matter of course. you have to get a license, but it is much easier. you just have to pass a knowledge test.

3000 people signed up to take that test already. it takes about 10 days to get a license going, but once that happens, you should be able to fly pretty much at will after that. there are a few restrictions -- you cannot fly over people, daytime only in low altitude. otherwise, it is really opening up this to a lot more people. emily: what do you like about these new rules? what don't you like about these new rules? >> what i like is that for the first time, you can go to an apple store and buy a phantom 4 and take a test at one of 600 test centers and get vetted, get insurance, and get your certificate to be able to be a remote pilot. and make the money back that it costs you to buy that drone in a number of weeks. that is exciting for the industry. emily: is there any area that you wish these rules went farther? or anything that you dislike about them? >> i can tell you what our

customers think. they have been talking about their nervousness around the waiver process. almost every provision of this new rule has the ability to submit a waiver online that you should have the right to fly near a certain airport, or in -- beyond individual line of sight, or other types of conditions that are normally prohibited. they are nervous about how much time it will take. time will tell. emily: talk about rules for hobbyists or the lack thereof? as i understand it, if you are i want to buy a drone and use it for fun, we don't have any rules to follow? >> yes and no. there are no specific rules, but you are supposed to follow the safety requirements of a community organization. basically what that means is it is very much similar to the commercial rule that you are not supposed to fly over people, go to high,

-- not supposed to go to high, not supposed to go near airports. there are certainly questions about how well that is enforced and we have seen hundreds of reports of drones flying near planes and whatnot. but, essentially, the rules are very similar. emily: i was speaking to the secretary of transportation, anthony foxx last week about this very issue and the fact that rules are hobbyists could go further. what is your take on whether more regulation is needed in that area or what? >> we do not think more regulation is needed. we think more education is needed. it is about letting people know what they can or cannot be doing, rather than any form of regulation. that seems to be working very well and the industry seems to be -- the before you fly campaign etc.. really making sure there is

material and every box to let people know what they should or should not be doing. emily: take a listen to what secretary fox had to say about the new rules and what industries they could help open up when it comes to drones. take a listen. secretary fox: it will open to many more uses, commercial uses. on the other hand, i think as we have commercial uses, hobbyists, airplanes, the integration of all those different uses into a single system is going to be the most complicated part of this. emily: so, let's talk about jd industries that it will affect most? there has been talk about agriculture, transportation. what do you see? >> on the ground, an imaging is the number one vertical. that would be things like real estate photography, event photography, wedding photography. anybody who is a photographer or

videographer is basically a drone photographer and will be going out to get a license. the remaining large areas are inspections, and that could be anything from roof inspections, cell tower inspections, any number of things that people inspected with human beings but are more efficient and safely done with drones. emily: what about amazon? how far off is an amazon drone delivering packages to my doorstep? >> amazon is doing most of its testing in cambridge and the u.k. right now. we don't really know exactly how far they have gotten. from a regulatory point of view, there are stumbling blocks that they and google and others wish had gone further. but the potential to obtain waivers for them. we have to see how the technology develops and how the process develops around these deliveries. emily: allen, as the person who is reporting on these issues, what do you think is the next frontier?

the next development when it comes to drones and drone regulation? allen: it really does feel we are seeing a critical mass here of change. we are going to see, by the end of the year, rules that will allow drones to directly fly directly over people and will be simple at first. just covering the drone with foam, so if it falls, it will not hurt anybody. the next step will give broader permission to fly long distances , so railroads, power companies want to be able to fly these things miles and miles over infrastructure to inspect them and use video links. once that happens i think we will see some tremendous growth, and then, after that, probably the deliveries we're talking about. emily: that was verifly ceo jay brackman and bloomberg's allen. coming up, doctors are examining

their hospital bed while they have the headsets on. for those trapped by their condition for long periods, it may be a welcome relief and help mitigate some of the stress of being in a hospital. >> it is kind of like a jail cell. i can get out and walk in every thing else, but you still end up in this 4 x 10 room. >> we need a virtual reality pharmacy. shelves of vr content that is evidence-based that i can map to -- reach off the shelf and map to my patient's needs. the more we had that, the broader the opportunities we can have to engage patients in virtual reality. this is not about silicon valley entrepreneurs. this is about when and whether we should interact technology with a compelling, human experience of being a patient. it is not a computing science or an engineering science, it is a social science. emily: that does it for this
