Perhaps. I just never found it useful to spend a day learning the failure modes and edge cases of a general-purpose library I could hack into my use case with enough wrapper code handling the impedence mismatch when I could spend a day building exactly what we need, with the added benefit of owning the code when requirements inevitably change. Like, I'll use numpy at least half the time for numeric code; I'm not a masochist; but most libraries just don't pull their weight.

Did anyone else have to maintain this code?

Of course.

at least we have claude now I guess

Meaning?
