> think there's a lot of code that gets written that's either disposable or effectively "write only" in that no one is expected to maintain it. I have friends who write a lot of this code for tasks like data analysis for retail and "vibe coding" isn't that crazy in such a domain.

Correction: it's a "cascade of 20 spreadsheets" that one person understood/understands.

Write only code still needs to work, and someone at some point needs to understand it well enough to know that it works.
