It's both.

The engineering part of programming allows us to learn from our mistakes. Things we did back in the '90s in Perl turned out to be more trouble than they're worth. Similarly things done in the '00s. I'm sure we'll look back on stuff done in the '10s with the same disdain, but if we're learning and evaluating based on what we've learned, I think we have a reasonable chance to improve.

    [Corion]: Meh. Once again I find that SQLite doesn't support window functions and I want to use those nowadays :-)
    [erix]: Look what I found! :P
    [Corion]: Hmm - actually, I don't need them, even though they'd be nice. I just want the (say) 10 latest images, and that's easily done with a limit 10 offset 0 clause, as I don't need all top 10 images for all users.
    [Corion]: erix: Sure, but this is for a really-lightweight application and I'm replacing a CSV file / JSON file for user configuration with SQLite (and optionally, Pg) :)
    [erix]: isn't a texty format handier for configs?
    [Corion]: So far, I've avoided having even a user database by storing the user information in a (signed) cookie that the browser keeps for me, but as I want to be able to lock users, I need a second storage option :)
    [Corion]: erix: It's needed for keeping the list of users and the list of tags associated with an image, and for keeping the images with users. I want an easy way to know if an image can be deleted, which means that it can't be referenced by any tag anymore. ...
    [Corion]: SQL feels like a natural choice here :)
