Why would you think there won't be jobs AI "can't do"? Have you used AI lately? It can do little stuff nicely. But when you throw something complex at it, you have to hand-hold it and give it many follow-up prompts. This is no different than any other type of automation ever.
There will be jobs that AI can't do. How many? Enough to keep 5-10 billion humans employed? What makes you so sure there will be?
Clearly AI has progressed considerably over the last 5-10 years. It's anyone's guess how much further it will progress -- maybe it'll plateau right where it is now, or maybe it will keep becoming more powerful as better algorithms are discovered. I'm not qualified to predict that, and neither are you, but the AI people certainly seem bullish about it.
You actually think money actually "just appears"?
Sorry, I thought you would understand that I meant that the resources that money represents appear, once you've solved the automation problems that currently make mass-production difficult. That's why you can buy a pocket computer today for $300 that would have your cost you billions of dollars twenty years ago, if you could have obtained it at all.
I bet you'd have more interesting conversations if you made a good-faith effort to understand what the other person was saying, rather than just jumping straight to the part where you get to throw insults at them and tell them how dumb they are. Doesn't that get boring?
