Back in 2019 Intel suggested the industry do this: https://www.anandtech.com/show/13405/intel-10nm-cannon-lake-...

But nm size is so baked into culture, it didn't take off.

TSMC now labels their process e.g. “N3”. So there has been a shift away from nm in some contexts.

But it really doesn’t matter. There’s not a single physical number you can extract from the process that accurately describes its performance. So just continuing to use “nm” and assigning some number that feels right is actually a reasonable approach.

It used to be MHz and GHz, then when that stalled, advertising nm became a thing. It can change.

Angstrom is kind of a fun word, so I’m sure a few nodes will be named after that.
