> if the system I'm using has excessive latency (more of a 90s problem than today) precision means even when I do mistype, I'm "feeling" it and backspacing, not seeing them (since they haven't echoed yet.)
Perhaps I'm just overly sensitive but if the input latency from keypress to echoing is consciously perceptible then I consider that already unusably slow. I can't imagine using a setup like that regularly. Special case being something like a slow SSH connection, where I do have to just "feel" it and proactively correct mistakes, but I fortunately don't regularly have to connect to servers more than about 200 mi away.
