There is one supplier of EUV lithography machines in the world, ASML. They are basically acting as an integrator for hundreds of highly specialized components manufactured to unimaginable levels of precision. Each of them has roughly one eligible supplier in the world who are operating at full capacity. To expand, they'll need yet another set of specialized and almost impossible to build equipment.
So the supply chain moves incredibly slowly, and the slowness is intrinsic due to the complexity and depth of the supply chain. It can't be fixed with just money. IIRC ASML is aiming to merely double their production of EUV lithography machines by 2030.
Sure, I didn't mean to suggest that it would be easy or fast to increase manufacturing capabilities, just that the confidence I'm seeing around AI should extend to the manufacturers (if that confidence for the future growth and success of OpenAI and Anthropic is warranted). That is, the business decision to increase RAM and GPU supply should be "easy".
