Is he wrong though? Sometimes you need to make a statement, like Apple not willing to do chatcontrol. Sometimes it's just time. It's time to drop empirical units, to much damage has been caused. My own language has so many exceptions to the "rules" that every generation spends a lot of time learning them (i.e. we say all 2 digit numbers backwards, it gets every generation, every time), again and again. It's like technical debt for a country. I thailand I almost died getting on the road with my scooter, because of the other side of the road rule.
Just bite the bullet, switch, feel the pain, but then, feel that sweet sweet relieve.
