I really agree with this take. I think the software and designs people stumble upon when they do things for fun and pure curiosity yield can yield interesting and thought-provoking stuff, that you wouldn’t have otherwise encountered when in “productivity” mode.

Do things to explore the design space, explore the most-unconventional idea, do something because it sounds hilarious, because who knows, you might just come up with something awesome, or your work/thoughts/failures/successes might inspire someone else and in turn they get the bump they need to solve some new problem! I don’t think this is limited to just “writing software” either, I suspect it applies basically everywhere.
