I don't think we have seen "all functionality" yet.

We have not seen iterative AI use for example.

The use case, where you tell the model "Solve this task. Then solve it again. Keep the better solution, then solve it again. On and on. Tomorrow, show me the best solution.".

And also not the "Run a company on your own" use case.

Those might make people and companies use models full-time. The price of that will be way different from current subscription prices. The TCO of a single instance of a SOTA model is on the order of $100k per year.

I believe that you're arguing "1% GDP increase due to AI is too conservative" rather than against "capturing 10% of the value increase is possible".
