Regardless of the specific mechanics of the bottleneck, we know what the proximate source of the problem is: openai locking up 40% of Samsung and SK Hynix wafer capacity for the next few years. That's what triggered the madness.

Is there an understanding of what OpenAI intends to do with that memory?

Surely they need GPU capacity and would need memory for those GPUs but OpenAI doesn't build GPUs or any hardware, right? So did they pay to keep the supply locked up, or do they have the ability to put that ram into use?
