"Right now, none of the above analysis applies because demand exceeds supply for frontier models, and supply is limited by a lack of compute."
It gets particularly hairy because models themselves can tune their "token verbosity" to manufacture demand for compute. If compute was such a precious resource, you'd think we'd be complaining that the output was too terse.
The ability for a vendor to determine ex post facto how much a query costs is a similarly new economic phenomenon to zero marginal cost.
A rational person isn't willing to pay more than the present value of future cash flows. Just like how a rational person wouldn't pay $101 for a $100 bill.
Where it gets fun is that: (1) we have people selling $100 bills for more than $100 and, (2) we have people gladly buying $100 bills for more than $100.
Yes, you'd expect the Falcon 9-based space launch and Starlink businesses to retain some sort of value whatever happens. They could easily be sold off as going concerns if things were to go south.
The failure of SpaceX might doom xAI and Mars colonisation, but it's very unlikely to wipe out American medium lift launch capabilities.
