Yeah, GDP with all its flaws is designed around economy based on buying and selling for prices. Interacting with other people. If you can really be rich and somehow do most things automatically without meaningfully hiring anybody (maybe only few people for simple manual labor for peanuts), at this point what is really the value of money? Except for maybe throwing minimal amounts to the masses. I can see the AI maximalist scenario taking us out of the monetary framework back into a medieval or natural economy almost.
