Well you say that, but I've had legit discussions with coders that use things like Dvorak because it allows them to type faster and thus code faster. I pointed out the actual typing of the code is the easy part and only a very small part of the bigger task. This one coder that swore by Dvorak had an impressive typing speed for sure, but also a reputation he could never push his commits because the linter kept spotting typos. And even then wouldn't get through testing because not all typos are caught by the linter. Of course he was the kind of developer that wrote 3000 lines of code before ever committing anything and testing for himself was beneath him, that was a job for the testers. Once he had lost a couple of days of work because he didn't commit/push and when he booted his machine somehow his files got corrupted and all was lost. After that he was in trouble for the nteenth time and was let go, shame because I liked the guy.

Using alternative layouts to prevent rsi I'm all for, but optimizing typing speed seems like not the way to go. I'm old and learned to type on a typewriter and later horrible 80s keyboards (although some were nice as well), so I don't care, as long as it has keys I'm OK to go.
