We've seen with GPUs that building more doesn't solve the problem. Large corporations buy up all the stock and the leftovers are still ridiculously expensive.
Unless there's something preventing the rich from treating supply as an investment to get even richer off of, increasing production only facilitates wealth collecting at the top.
That's not true. You are seeing a massive bubble in AI infrastructure unfold that is gobbling up gpus faster than we are increasing supply of gpus. That bubble will pop at some point (probably soon) and things will get more normalized int hat market too (unless that pop coincides with something really stupid happening like China invading Taiwan, which would take out massive amounts of production capacity)
