OpenAI found the answer: artificially curtail the supply of DRAM wafers (by buying 40% of world's supply without necessarily having a feasible plan to make use of all of them], to prevent consumers from getting access to gpus with more and more memory, which could allow them to get dangerously close to the state of art while running local AI

Rather than an increase in VRAM of consumer gpus, we are seeing a decrease, which is pretty optimal for OpenAI
