I think either you haven't used LLMs for coding in a while, or you're working on things where they might still be limited on.

I've been able to use LLMs to build things in a weekend that I would not have been able to do in the past, without putting in months of serious effort.

I recently rewrote from scratch in a weekend a project that i had made a couple years ago. In a single weekend i now have a better product than I did at the time, when I spent maybe 20x the amount of time on it.
