Why do stage musicians use wireless microphones? Is it because they have a hatred strictly for aesthetic reasons? Nobody said you can’t use your damn wired mouse if it makes you happy - but latency is not an actual reason to prefer a wired mouse. > Again, wireless can be superior, but only when you are deliberately cherry-picking the least efficient wired setup to compare to the most efficient wireless setup, just like your argument for mice. But earlier I thought you said it was a law of physics that conductive mediums were always superior to air. Also that the speed of light in air is slower than a “conductive” medium. You don’t seem well.

No argument here! Great points.

No, not right. As someone else pointed out a point to point link through the air will have lower latency than fiber (glass or plastic). Whether or not a signal can be carried accurately and error free through any medium involves concepts beyond a basic understanding of the speed of light. But in the real world one will encounter reliable well designed wireless links and poorly performing wired links.

There's a clear misunderstanding here. Light and wireless signals used by mice etc are the same thing though, just at a different frequency. They propagate at the same speed, the speed of light, which ironically is slower in glass. Wireless signals in air travel faster than light in a fiber optic cable (and faster than electricity in copper).
