and but very good, and this is difficult as all of those algarhythms are and tying all of the camera work and everything into the controls of cart and probably one car talking to another car and one car talking to signals and all of that kind of stuff and when those cars come to san francisco, and they try to run it and someone spends $30 million to provide taxi service because that is what it will be is driverless taxis and you will have to come and say that no one will have to park again, how are you going to make your 200, 300 million dollars a year that you need from parking cars? so i am trying to say to you, start early, this is going to be a more difficult problem than even the gaog the algarhythms and all of the state laws for you to negotiate the drop that has to be a very able drop, i mean, if you want to take your google taxi downtown at 8:00 in the morning or 9:00 in the morning that is a major drop, if you want to take it from a bus stop to your home, late at night, there is no drop at all. you know a nickel and a dime for a mile. so start soon, thanks a lot. >> next spe

>> they said this was an algarhythm, which is math, which terrifies me.an algarhythms know so much about you. i'm convinced i was part of the negative group. it's really about perspectives. it's just too much. i was wondering why do i keep seeing this? now i know. >> they say positive pictures from other people's lives are depressing, andy. but you wouldn't know about that. do you grow with this? >> yeah, it makes it legal because of the terms of service. but it doesn't make it okay. this is bad stuff. you don't do psychological experiments on people without their consent. it's unethical. >> every advertisement on television is -- >> no, it's not. >> they don't tell you this is a psychological experiment. >> i don't know why anyone would continue to use facebook after this. why is it didn't from the nsa? because i can opt out of facebook. if can i opt out of the nsa, i'm for it. if i called it obama's nsa, you would agree with me. >> it doesn't work on me. that's a psychological test. >> and you failed. >> i think tom is onto something. this is exactly wh

what evidence do we have that the algarhythms you're running are showing anything viable. >> yesterdaydisagree it's illegal, there's no disputing the fact the nsa has been proven incapable of safeguarding the data. the nsa should not be allowed to collect and store it. what do you think of that line of argument? >> i think about this part of it a lot. so a lot of the snowden documents come out of essentially the consultant presentations and anybody seen a consultant presentation knows they are not wholly accurate and tend to suggest that the project is going better, that it is more foolproof and technical capacities are more overwhelming. you look at what we see when the government does technical projects, we think about healthcare.gov and think about the incredible disaster of the scheduling systems at the va, those are really bad examples but it's not like you get examples of tremendous insane technical competence without mistake from any part of the government. the thing i often worry about the nsa is essentially two fold, in addition to the very serious privacy and legal concerns,
