Interesting! I'd always heard that the nanometer wars were mostly marketing fluff these past several years and the quoted numbers divorced from reality, but they're claiming genuinely sub-nanometer chips. And 3d chip designs, which is equally impressive. I haven't followed chip tech in a few years, but last I knew heat dissipation was still a huge bottleneck preventing stacked designs.

Though it's a shame they're focusing all that innovation towards the AI sector. Their consumer lines have been stagnant for a while now.
