Will lower memory availability to consumers increase reliance on cloud-based storage and demand for data centers? >

No, because you need more RAM to run a smart terminal than a standalone micro, because there’s no secondary memory available to rely on.

Therefore, according to our best estimates, OpenAI likely needs less than 30% of the 10.8 million wafers it’s planning to buy

OpenAI hasn’t actually paid for any of that, its sold on credit with a 6 year repayment period on hardware that will only last 2-3 years at most. That’s why no memory manufacturers are increasing capacity, as they would if they thought there was any long term increase in demand.
