The US National Semiconductor Technology Center plans a collaboration with new Japanese chip research institution (unnamed in these articles) to produce 2 nm chips by (or as early as—I've seen it reported both ways) 2025. This was announced in June 2022, but I didn't find out about it until today; and since I haven't seen it posted elsewhere on this site, I thought it worth sharing.

The new chips would offer a much higher performance while using less power. It could also help ease the chip shortage.
