Having written scientific numerical software for decades, and having been in situations where I want high speed or I want reproducibility, and having worked with hundreds of developers, I agree wholeheartedly with Gustafnot - the vast majority of developers prefer performance over bitwise reproducibility. Lose a few bits here and there, and most don’t care, because they treat floats as fuzzy to begin with (and almost never care about reproducibility since it’s very hard to obtain due to compilers, libraries, etc.) . But slow down code, and they sure notice quickly.

If you really want to claim the opposite, do you have evidence? Or experience that it’s true?
