I don't know what the real number is. People are going to say, are you telling me we saved twenty-five thousand lives by not driving? And then we can bank that savings and always save twenty-five thousand lives a year? Or for the full year maybe it's fifty thousand. Could we save fifty thousand lives a year just by having self-driving cars that would almost never crash? I mean if you did it right they would never crash. So I think the self-driving cars just went from something you'd like someday to, my God, why don't we hurry up on this? Because you could save fifty thousand lives a year. That's as much as we closed down the entire economy for.

I think contact tracing is going to be a thing. Did you see the story that I guess Apple and Google have decided to release, I don't know, some standards, technical standards or an API or something? But the idea is that they're making it possible to build apps where you can tell if you've been near somebody. So let's say you were diagnosed with having coronavirus. You could, with a few pushes of whatever buttons on your app, and maybe you don't have to allow it, I don't know if you have to give permission or whether the government is just going to do it. At some point you have to give permission. So maybe you give permission from the get-go, say it's before you've been diagnosed, so that your Bluetooth is telling you who you're bumping into all day who also has a Bluetooth on. So the idea is that you could look at the digital trail and you send people a text and say, hey, you stood within four feet of this person who has coronavirus. Go get checked or something like that. That could be huge.

You know, if you were going to make a short list of all the things that could get you back to work, well one of them would be widespread testing, which we can't do yet but you know maybe in a few weeks. The other would be magic, of course, which doesn't exist, so that would be great. And then we have this new thing which is these apps that will do the Bluetooth contact tracing, which doesn't exist but one imagines that in a month or so maybe we could have something like that working. But all of those, and maybe the hydroxychloroquine makes a difference, maybe genetic testing will tell us something. So we probably have four different ways that we could attack the virus. So I think we'll get there.

I think education online will change completely. I think the biggest thing that will change online education is the first time somebody does it right. In my opinion it has never been done right. No, it's not like I've seen every online course but nothing I've seen, and what I mean by doing it right is something that takes like a Hollywood movie kind of a model. And they hire somebody who's just good on camera, looks good, talks well, somebody to write the script, somebody to do the graphics, somebody to direct it. So you've got like a real movie production but it's just a college course or a class. And once it's done right, and especially you would also do a lot of A-B testing so you might test it out with small crowds before you finalized it to make sure that you're saying things clearly, etc. So to basically produce a class the way manufacturers produce any other product, which is it goes through testing and research and polling. You've got a team of experts coming together. It's a long-term project. Right now we just point a camera at somebody who knows how to teach and they just teach. But as soon as somebody does it right the first time it's going to turn into a real business.

And it might be, I would argue, all right, here's another prediction. I will argue that the biggest business of the future will be online training. Yeah, how do you like that prediction? I'll say it again just so there's no confusion. My prediction is that the biggest industry in the future, the one with the most dollar amount, will be online education. Because the courses are going to be, you know, colleges will eventually have to disappear because they don't really make sense for the price for what you're getting. They just don't make any sense. So I think regular colleges will start to fade away. Online education will grow and just keep getting better. And I think that when people are producing, imagine what you would pay. Just think about this. Imagine what you would pay to have a course that you needed, let's say you needed it for your job or it was part of a degree program, but you could take the course that was as fun as watching the best movie you've watched. Like it's just really entertaining but you're also learning at the same time. How much extra would you pay for that versus the boring one that makes you want to take your brain out with a spoon? Well you would pay a lot for that. Not everybody, but there would be enough people with money who would pay a lot for that training that's a little bit better. And I think eventu
