GP has provided an anecdote with no supporting evidence, nor any code examples. So it is as fair to assume the story is a fabrication as much as it is to assume it has any truth to it
Yes! You should absolutely always assume a random stranger on HN is outright lying about a trivial anecdote to farm meaningless karma.
I am really shocked at the response this trivial anecdote has gotten.
I could state it much more generically: we had an annoying Excel sheet that took ~10 minutes a week, I vibe coded a command line tool that brought it down to ~1 minute a week. I don't think this is unusual or hard to believe in any way.
