It'll come in time. Gradually we'll get to a situation where the hoops we have to jump through to run a money system in circumstances where free availability makes more sense will just get too complicated, and the system will just fade away. There are aspects of the Internet experience that presage that.

There's no automatic link between a money system and "human nature". As I said, there was a time before money, and there'll be a time after it. We were humans before money, and we'll still be humans after money.

But the change probably won't happen in our time.
