Gates are about 30-50 nm wide, even though they're called '3nm' for marketing reasons.

Metal pitch is 26nm. That means parallel wires can be placed 2 wavelengths apart with 13.5nm light.
As The Register used to call it, these clean-sounding process nodes (15nm, 5nm, 3nm etc) are "marchitecture." Marketing architecture. Reality is much messier.
Like free range chicken.
You only need to live in reasonable place for that phrase to have a proper meaning, across whole market from cheapest to most expensive.
What is 'proper meaning'? Only a single brand of egg in my supermarket is genuinely free range per the definition supplied by our agricultural scientists (CSIRO, Australia) - less than 1500 hens per hectare. "Free range" can mean anything up to 10,000 hens per hectare.

They have a code in my country that is pretty simple from 1 to 3. The highest tier is 11 chickens per square meter apparently (I do not eat poultry myself).
