i think the latest is that china has managed to create a GPU that’s ~7 years behind. i’m not sure that’s “a GPU from 7 years ago” or “it will take them 7 years, acknowledging that there’s a known path so will take less time”

AFAIK they’ll have to figure out EUV or some other method of lithography at that scale, which they’re trying really hard at but it’s one heck of a difficult thing to do which is why only TSMC currently actually has it working
