> Also some people just find it fun to go through their Anki deck instead of doomscrolling while on the subway or waiting in line. Whether there's any real benefit for that person is debatable. It's “fun“ in the same way going to the gym, or drinking kale smoothie is fun.

I'm probably one of those people, but commuting is one of those examples where you have a small (hopefully) amount of relatively low value time, time that is somewhat interrupted. What else of value would you do in it? Maybe listen to a podcast, catch up on blogs. All fine, reasonable choices, but doing a bit of Anki is a reasonable alternative.

Only time I feel like I've wasted those periods is when I end up wasting it (just scrolling through social media or random videos). Anything else is I think a reasonable choice.
