My skepticism turned into a realization when I first asked an LLM to write anything nontrivial, and it just breezed through it. I am curious why many projects mentioned here seem to take people only a few hours or a weekend at most. I have been using LLMs to help rewrite the Ytree file manager originally written in nineties C. While the AI enables creating code of this complexity, the project still demands months of persistent effort.
