bulwark against fake news eventually, but that you can just ask a question like that and get such qualified responses? It's just ridiculous. It's ridiculous.

Likewise, have you noticed how many times Elon Musk has responded to average Twitter users in the last few weeks? It really is mind-blowing every time I see it because a lot of the people he's responding to are people I know from either Twitter or real life or both. And to see how often he responds to a valid question that catches his interest, it just makes the world seem so small but also it makes the world look like it's working. That the person who has the best information on stuff can answer the question.

I'll give you an example. There's somebody on Twitter talking about he was testing, I guess, Tesla's current version of their self-driving car software and said something like — I guess it was a study that says it was eight times safer than human driving. Eight times safer than human driving. And Elon Musk saw that and he tweets, "This trend will be well over 10 times safer with the update that they're working on right now, the software update."

So think about that. The self-driving car is already — I don't know if you can really measure this because there's no way to know what self-driving cars would do at scale. That's got to be different than one car. But there is a study, if you want to believe studies, that says that it is eight times safer than human-driven cars in terms of accidents.

Now why did Elon Musk feel he needed to weigh in on that point and to modify it from eight times as safe to 10 times? Because that's not much of a difference, is it? If somebody told you something was eight times safer than the alternative you wouldn't say, "Whoa, I'm not going near that until it's 10 times safer," would you? Literally there's no, in terms of your decision making, there is no difference between eight times safer and 10 times safer. Two times safer would be enough. That's all you needed. Your decision would be a no-brainer at two times better. But eight times better, there's no conversation. At 10 times better you wonder why you even had to update it. Well why do we even care if it's eight times better?

Well here's why. Have I mentioned that Elon Musk understands persuasion better than just about anybody? I mean he gets it right all the time. All the time he gets it right. Here's another example. 10 times is way better than eight times not because it's numerically better. I mean it is. That's a pretty big difference. That would be 25 percent bigger, right? So that's a big difference. But that's not the important part. The important part is our brains are tuned to big round numbers. No reason. It's just what we've been listening to. We're used to it. And so 10 times, that's the number you can sell, right? Eight times better is technical data. 10 times better and you can make the sale.

And the sale is we need to change the law so self-driving cars are here because they're 10 times safer. I mean just think of that. 10 times safer. That's a marketing number. And there's a reason that Tesla doesn't have a marketing department and that Elon Musk literally runs the marketing for Tesla while he's tweeting on the toilet. I mean not every time but enough of the times that it's impressive. And here it is again. Simply by emphasizing the 10 times versus the eight times he's done what his marketing department couldn't have done for him. And it comes from him so it gets more attention. So it's basically he is very competently replacing marketing with just tweeting. I mean he actually is doing that. It just doesn't seem like it's possible but he's doing it right in front of you.

All right. Speaking of technology there is an amazing, amazing story that I believe no one else has discussed and so I will discuss it now because we're right in
