I mean, putting in a bit of thinking before you actually hit the keyboard can be an incredibly effective form of optimization, if you can get for example an O(n^2) down to an O(log n). You’ll even save time on not having to rework the thing later, and if you build on poor foundations, chances are you’ll stumble upon fundamental architectural challenges down the road, which can be extremely costly in terms of development time.

Jellyfin is better anyway

I wish this were true, but as a multi-year Plex-to-Jellyfin migrant, I have to point out that Plex was the better software.

I still choose to run Jellyfin for other reasons (don’t like the commercial path Plex is taking, among others), but I still do miss the better reliability and larger feature set in the Plex software stack.
