I seriously doubt these could be mass-produced in any meaningful way due to the rarity of the requirements. I’d love to hear a more practical argument for this though.

“2D” fab isn’t new, and correct me if I’m wrong, that is sort of how AMD got its start. It’s just the idea of fixing heat dissipation to solve for Moore’s Law, but requires novel materials that didn’t exist yet. This has cropped up in various forms for metal and silicon dynamic replacements over the decades, and I think the last big news I heard about this was 10 years ago regarding graphene being a cheap and plentiful replacement for silicon, and here we are with no proofs of concept.

It’s a paper I guess, but not anything that has the feasibility of showing up in the real world. If anything, I think these labs are working on shrinking quantum computational units down to be more useful for everyday computing, since they kind of already “work”.

Edit: also some recent news about transistor heat dissipation.
