Which is software written 1966, but the web version is a little newer. Does occasional psychotherapy assistance/brainstorming just as well, and I more easily know when I stepped out of its known range into the extrapolated.
That said, it can vibe code in a framework unknown to me in half the time that I would need to school myself and add the feature.
Or vibe coding takes twice as long, if I mostly know how to achieve what I want and read no framework documentation but only our own project's source code to add a new feature. But on a day with a headache, I can still call the LLM a dumb twat and ask it to follow my instructions instead of doing bullshit.
But, vibe coding always makes my pulse go to 105, from 65 and question my life choices. Since few instructions are rarely ever followed and loops never left once entered. Except for on the first try getting 80% of the structure kinda right, but then getting stuck for the whole workday.
