I think it was @david_chisnall who pointed out earlier that coding LLM's will become much less useful when we stop doing (expensive) training to keep up with breaking changes in API's.

Well, I just spent two hours trying to fix some code that was buggy because the API changed less than a year ago and came to the decision of reading the F manual and write that 200 LoC myself.

(to be fair, I think this would work if the LLM had access to a complier and runtime)

Stats:
- Rewrite done in 45 mins (incl. coffee)
- LoC 200 -> 110
- Complexity ~halved (two-pass -> single-pass processing)
- I actually know what the code does
