Real assets have utility of their own (i.e. a house to live in, commodity to build, etc). Money only exists to incentivize human economic actors to bother working, to relative price resources against each other and for governments to use as a tool - it isn't wealth on the aggregate scale.

AI invalidates a lot of the need for money to even exist as a concept anyway in some scenarios. If only a few people have all the stuff (huge inequality) you don't really need a large money system because you no longer need most people to get what you want (i.e. most are economically irrelevant). You have a magical genie called AI instead that can transform what you have into what you want as long as you have the raw materials, space and energy. The wealthy could then negotiate in large transactions via barter - I trade that plot of land for that copper mine. Most large transactions are negotiated in any case.

A very likely case (there are others) is that AI enables feudalism of some sort to come back - where the new lords are the owners of the other economic factors of production that remain scarce (capital, land, resources, social) - not intelligence and/or labor. This is the opposite of a meritocratic society. It would explain why people want to win the AI race; and are willing to burn uneconomic amounts of money to build it out. There is a race to the finish here.
