An interesting implication of this is that AI inference and training has a path to a ~3x hardware cost reduction (and maybe ~2x total cost reduction) without any technical innovation whatsoever, we just need to wait for dram supply to meet demand (either by manufacturing scaling or just waiting for the current rate of manufacturing to fill the demand spike).
The memory makers will not expand demand drastically. It is in the nature of their business to keep the market under-supplied, otherwise the following oversupply will kill them. Instead, supply is just rerouted from less profitable segments such as mobile and personal computing.
I'm guessing you are also probably unfamiliar with the terms like "chicken game" which refers to the cutthroat, high-stakes price wars where dominant semiconductor manufacturers intentionally overproduce and slash prices. This is literally how the industry went from dozens to just three majors today since the 80's.
