want to leave room for an unplanned connection. like serendipity is a huge driver of progress and he put it together and that is one of the reasons i think that we are heavy on intellectual property restrictions and patents and things like that in society because some fluid collide with other ideas creasing this kind of freedom and flexibility and it actually can drive innovation as much as the proprietary nature and i think the balance is a little bit off. but it's also that the unintended consequences are often where the problems are. generally when someone steps up to solve a problem, eventually

they do and the solution is better than what came before this. there are very few cases in society where we elected inferior technology like the betamax and vhs story. so there are complicated reasons and we chose the worst technology. but that doesn't happen very often and then 10 years later we had dvds which makes the whole thing kind of obsolete. so it is the local market progress that tends to talk about this. the problem is the effects. and that includes air-conditioning get invented initially with an industrial technology and then they put in a movie theater for the first time which made the summer were popular. no one went to the movies in the summer until air-conditioning came along because many other

people needed to be in cooler temperatures. so triggers the single digits where everyone moves to the sun belt in florida and the desert states and places that are basically uninhabitable. the truth is that's really out there and that rewrote the political map of the united states. so there is a huge swing in the electoral college and it also creates these desert states that have huge populations and locally it solves the problem of how do you keep people cold in a hot environment. and the hummingbird effect is that you have to get his people water and that's too hard to do and there may not be enough water to support 10 million people living in the desert.

and so that is why it is very important our eye open because that is often where the downside of the march of progress comes from. and oftentimes we have a new set of technology as well. and i think we have time for one more question and it's going to be all the way over there. >> hello, i was wondering if your children are passionate about the curiosity with so much enthusiasm about the development of culture and inventiveness. from the things that you have studied to help support back, did you look at good ways to help them develop this? >> now you're making me feel bad about my parenting.

[laughter] i've been so busy that i don't have time for my kids. [laughter] >> okay, i wrote this book and it was all about and are a science of everyday life and that was the subtitle. and so i went and did all of these experiments and i took a couple of mris recreationally. most people don't do recreational mris. and it was like, what consigned to do about yourself as an individual. not just how the brain works, but how you work. and i had very young kids at that point. i have a 2-year-old and i had my second boy and i had someone say no experiments on the children. [laughter] and so i probably haven't been as good about it as i should be

given how interested i am. but what i found now that i'm older is that part of what you have to do is to figure out that they are going to be into things that i am a little bit suspicious. like luxury yachts. so the way to deal with that is that i was in the other things and you should be into this or that like i was. but rather to take this and just kind of spirit towards thinking about it in a richer way or adding new skills. so i got into the bizarre habit of building this up in various social media forms and then selling them for small dollar amounts. he has a bunch of followers and the currency is all itunes

gift cards and stuff like that. and my wife was like, what is going on. and i said he's doing this kind of arbitrage between these different account. and their like were going to set up a spreadsheet and every time that you buy an account or sell an account, are going to keep track. and this is going to teach about how this kind of works. and so now we have this and i think as a parent you just have to kind of -- your kids are always going to scare you into the new things that they get into that you're not always going to approve of area and so what you have to do is be like

well, let me show you some things along the way that will make it even more interesting letter saying that i want to do this over there. and so that's just, that's my parenting advice to you. [laughter] >> thank you guys so much. always so great to be here. i really appreciate it.
