From TFA>>I'm open to suggestions how this is going to play out. Close to a trillion dollars invested in AI. Where will the money come from to recuperate all these investments?

If investors are looking for a 50% return, they need the investment to be worth about $1.5 trillion. If they're looking for a 100% return, it needs to be worth about $2 trillion. That's still an enormous hurdle, but it's much smaller than suggesting AI needs to somehow generate trillions of dollars in cash simply to recoup the original investment.
