I just wrapped up a project where I had to do a bunch of work with audio, which I’ve never done before, and I wouldn’t say 100X but I did at night over a handful of weeks what would’ve taken me months to teach myself and some of it I probably never would have figured out. Like I could prototype on an easy library and go “rewrite it with librosa instead” or “nah I don’t really like this let’s just do such and such with ffmpeg that would work and probably be faster, right?” or “find a way to do this funky thing with torchaudio and a bunch of file I/O in memory” and then be like “how much money would I save on GCP egress if I did such and such?” It’s not always right on the first try but omg does it save a shitload of time and energy.
