That definitely happened with Uber, but I would argue that one key difference between the Uber situation and the AI situation is COST. How much can COGs be reduced via optimization and technology.
In Uber scenario, the cost is labor, there's a hard lower limit where people will find something else to do for work.
In AI scenario, we've already seen the labs make major reductions in cost-per-token. I think it's fairly uncontroversial to say they have more possible cost reduction levers than Uber.
So I don't agree that at some point VC money will run dry and the unit economics for tokens will dramatically change.
