I would argue those days are coming back. Thanks to LLMs, I have probably 10x more "utility" scripts/programs than I had 2 years ago. Rather than bang my head against the wall for a couple hours to figure out how to (just barely) do something in Python to scratch an itch, I can get a nice, well documented, reusable and versatile tool in seconds. I'm less inclined than ever to go find some library or product that kinda does what I need it to do, and instead create a simple tool of my own that does exactly what I need it to.
Just please if you ever give that tool to someone else to use, understand, maintain, or fix, mention that it was created using an LLM. Maybe ask your LLM to mention itself in a comment near the top of the file.
