I just want to point out that most keyboards hav a latency at 10-20 ms[1], so 1 ms is impossible.

Is there a physical reason for it? Or is it just that keyboard manufacturers don't care about latency?

That includes the physical travel time, which is an extremely important caveat.

Sure. But that is what the experience is, right? When I press a key, the entire end to end latency is what I care about.
