our walter isaacson chose burns why he chose that subject. >> why the mayo clinic? >> i think we have always looked over the course of 40 years of stuff that is uniquely americans. each of the films hold up a mirror of what we were and tell us about who we are now. i was drawn in, sucked into the mayo formula. and i knew it had to be counter balanced with contemporary stories. if i hadn't done vietnam, i don't think i would have managed this well. the ability to jump ahead to the present and look at things. we concentrated for several years on this project. when we finished it and stood back and looked at it, we realized we had something that was talking about the current health care crisis without having to get down into the moras of the politics of it. here is a great model of something that worked and rather than get into the he said she said stuff, you could look at say, here is a recipe of something that works. let me show a clip from the new mayo clinic documentary, it is really about value and personality. >> melanoma is one of the most common cancers that co

my colleague walter isaacson has spoken to someone who saw it from a privileged position inside the silicon valley castle. walter, you've just been speaking. tell us what he came up with. it's alex stamos, chief security officer for facebook. as we went up to the 2016 election, this is not a job in retrospect you wanted to have. and we talked about how the evidence started coming in that the russians were both hacking our elections and then using young kids to try to mess with our minds through facebook. and the frightening thing about this interview was he said nobody's trying to stop it. the republicans have blocked any plans to try to halt this. facebook is making some efforts, but not enough, and it's too late to stop it for the midterms this year, but we got to start working now if we don't want the russians to hack us in 2018. listen to what he had to say. >> you were chief security officer for facebook in the 2016 election which seems like a pretty tough job, especially in retrospect. when did you start getting a sense that something was going definitely awry with russians hacking ou

i was about to say, jews who don't believe in god were drawn to that aspect, walter isaacson, in his biography of albert einstein, described albert einstein as an atheist who believed in god because einstein felt, unification, to understand what he kept searching for. and literally, jews say i can't believe in god and has sally writes in her book, never liked the term seeking or searching. i think searching for that meaning and for that ideal is what unifies judaism. >> quite a few colleagues would disagree about belief in that sense. what about the concept of shabbat? is that not dating back to as russia, the one thing that all observant jews would affirm? >> it is more honored in the breach as they say. >> the almost answer to my question, you addressed it when you talked about geographic loyalty of jews in the south and in the north during the time of the civil war but you didn't directly say anything about the issue of slavery among jews. any difference, were jews any different in the fraction that were concerned about the morality of slavery versus those who saw it as an economi

here is walter isaacson, professor at tulane and an alumn of "time magazine" and time, inc., as am i.alter, good to see you. >> hey, tyler, our old company. >> our old company has -- where has it gone? well, part of it -- >> he paid a high price. >> he paid a high price for a property that apparently has an operating profit in the 30 to $40 million range. was the price right? >> well, you talk about what was in that price, with liabilities, subscription, database rights you have, but i trust mark benioff, if anybody knows how to price something, he does he's doing it for the right reasons. you could have had different private equity funds, others come in to do it, try to break it up or milk its circulation base here's a guy doing it because he believes in it, believes in the brand and i couldn't be happier. >> it -- talk to me a little bit about the advantage of having a sole proprietoproprietor, wheths benioff or luce who started the whole thing about 95 years ago as opposed to having a corporation own it which is better? >> you know, we always argue that back and forth. we can talk

joining us, cnbc contributor, advisory partner of walter isaacson, and casey newton in silicon valley we turn our attention back to business news. walter, i don't know what you find most interesting, the incremental steps on product or the degree to which their supply chains may change or not the president did hint they had plans to create new plants in this country >> right first start with the incremental changes in product i think it would be good to have a less expensive iphone and new grander more expensive iphone. i remember when steve jobs was running the company or when he came back to the company in the late 1990s, what they had done is milk the mcintosh product line, had six different variations, and xs and xss and xrs. he said it is ridiculous, hard to know what to buy. he insisted they simplify the product line and innovate another line, such as ipod and iphone i think at some point sort of giving up the iphone product line is a good strategy for the time being, but it would be nice to have a truly innovative product, and that would transform the company more than argument

so let me start with walter isaacson, he is a history professor and most recently author of leonardo davinci. and alicia men mendez. and harri sreenivasan. and michel martin. and welcome to all of you. we are a team. and we are so excited to be expanding this version of this program. and i just wondered and let me start with you michel. what does this mean to you. what makes you hopefully excited about being in this program. >> you stole my thunder. we are all exited -- excited to be working with you. i think we see with the success of podcasts that people are eager to have a conversation that isn't over in four minutes. what you can actually dig into nuance and dig into a place that people don't have time to talk about. >> you are right about the podcasts and you do host a podcast as i said. people seem really thirsty, drinking up to slate their thirst on trying, trying to make sense of what i think anyway a massively complicated up ended world by now. >> people look at the news and think what does it mean, what does it mean for me and my children. how can the sitting in front of me

for more on the continued turmoil, we are joined by contributor walter isaacson and sus susan lyons. if the departure for the executives wasn't enough, back and forth between marcus and acton says a lot about culture at the company, who has responsibility for the position we find ourselves in as a country and planet, regarding social media what are your thoughts >> it says a lot about the culture. it says a lot about the business model, you have to monetize people that use the service to sell access. you are going to end up doing everything you can get away with i think the most important thing that brian acton said and it wasn't a low class statement, he is one of the what's app founders criticizing facebook, he said we were trying to find out revenue models, including charging somebody a tenth of a penny for a message. that may seem not -- it isn't thinking out of the box, saying can't we have another revenue stream that doesn't require us to sort of violate the lives of our users. >> something about this seems off to me. overall with all of the turmoil in silicon valley, they have
