That industrial revolution thing worked because it became invisible--we don't have the big motor turning everything; we have like 50 motors in our homes that became invisible. So, to some extent, this stuff is working because we don't see it. Because it's not something that is visible. And it succeeds to the extent that it transforms while we don't see it. So, that's one thing. And the second thing I would say about that is that, we're sitting on this huge wave of the First Industrial Revolution which brought this incredible prosperity to us all, the fact that we see around us that we no longer in the agricultural hunter-gatherer era were--we had to do everything with human muscle or with animal muscle, animal power. We invented something called 'synthetic artificial power.' And we harnessed fossil fuels, and carbon fuels, to give additional power that we couldn't do. And all that we see is basically a result of this artificial power. So when we drive down the road in your car, you have 250 horses working for you at that moment. Just turn a little knob, you've got 250 horses powering you down to do whatever you want to do. And then we distributed that power through a grid to every home and farm in the country; and so farmers could employ that artificial power to do all kinds of things; and factories could use that artificial power. And everything that we had built around us was because of the artificial power that we made. Well, now, we're going to do the same thing with artificial intelligence. So, instead of--in addition to having 250 horses driving you down the road, you are going to have 250 minds--which we are going to get from AI, from artificial intelligence. And that, we're also going to put that onto a grid and distribute it around the country so that like any farmer could justget and purchase as much artificial power and artificial intelligence as they want, to do things. And just as that artificial power, was this incredibly transformative, incredibly progressive, incredibly powerful platform to give us all that we enjoy now, this artificial minds that we are going to get on top of the artificial power is going to transform us in an equal way: it's going to touch everything that we do. And I think actually it will transform us more than that first Industrial Revolution did.
