With Advent of Code coming up I've written a blog post about solving coding challenges with functional programming. Maybe someone reads it and recognizes that you dont need deep understanding of type theory or monads to get started with the cool stuff. Examples in OCaml.

I'm challenging the narrative that "A.I." is a multiplier in the hands of experts. I see it being repeated everywhere, but there's no credible evidence.
If anything, an expert sees more problems in the output and spends more time fixing them. "It would have been quicker to write it myself".

LLMs don't say "I don't know" when they don't know. Because they have no way of knowing they don't know. Because they don't *know* anything.
A factually accurate response and a completely hallucinated response are the same thing to these models.
