> Dvorak isn't particularly better because typing speed isn't worth optimizing for if you are good enough

Is Dvorak even quicker? I tried learning it and found some quirks, for example, lots of English words end in "ght" (thought, bought, draught, taught, etc...) which is extremely awkward to type on a Dvorak layout (you need to strike all three with one finger whereas on QWERTY it's split between both hands so you can alternate).

I agree with your point though. I type 80+ WPM on QWERTY with no maintenance and honestly, I type way faster than I can even think about what to type (especially for programming). Now that my college essay days are way behind me, I don't think it even matters.
