for desktop I prefer mpv

not sure if I would, but I will definitely not rule that out. I think almost anything you learn changes how you think and can express your thoughts, although language does it in a more direct way.

in many cases, it’s the only language that all participants in the conversation understand, not the only one for each.

but to be honest, if I could exchange my knowledge of my native language with the same amount of experience with something else (e.g. programming, math, etc.) I might take that deal (after moving to a primarily english speaking country of course).
