If it ends up AI only makes a little profit annually in the longer term the whole thing collapses on itself.
Because "making little money" is a commodity business activity, overrun with competition from Europe and Asia.
So why would you ever want to compete in the race to the bottom of "little money" when you have the highest labor cost in the world? It makes no business sense.
You go into "all or nothing" moonshots because Europe and Asia can't compete there. Especially when you have the world reserve currency as the infinite money glitch cheat code (while it lasts).
