I love this one for an exploration of that question: Charles Stross, Accelerando, 2005
Short answer: stratas or veins of post-AGI worlds evolve semi-independently at different paces. So that for example, human level money still makes sense among humans, even though it might be irrelevant among super-AGIs and their riders or tools. ... Kinda exactly like now? Where money means different things depending where you live and in which socio-economic milieu?

nb I am not endorsing Austrian economics but it is a pretty good overview of a problem nobody has solved yet. Modern society has only existed for 100ish years so you can never be too sure about anything.
Maybe it means a Star Trek utopia of post-scarcity. Maybe it will be more like Elysium or Altered Carbon, where the super rich basically have anything they want at any time and the poor are restricted from access to the post-scarcity tools.
I guess an investment in an AGI moonshot is a hedge against the second possibility?
