can we please socially murder the sales/marketing team that rebranded the unit in nodes from something physically meaningful to a random countdown detached from reality? (1nm node does not have any bearing on critical dimension or size of the circuits)
To be fair, the industry spent decades measuring a distance, so when they started doing features that had equivalent effects, the easiest way for people to understand was to say something akin to equivalent size.
Of course, then we have things like Intel releasing their "10 nm* process, then after TSMC’s 7nm process was doing well and Intel fab hit some bumps, they declared their 10 to be more like a 7 after all… it’s firmly all marketing number…
Problem being no one is suggesting a more objective measure.

The best thing you can do to understand this is watch the latest Veritasium video about ASML.
ASML figured out how to make ultraviolet light very close to X-Ray wavelength using some incredible physics and engineering.
