LLMs can pretty reliably write 5-7k LOC.

If your needs fit in a program that size, you are pretty much good to go.

It will not rewrite PCB_CAD 2025, but it will happily create a PCB hole alignment and conversion app, eliminated the need for the full PCB_CAD software if all you need is that one toolset from it.

Very, very, few pieces of software need to be full package enterprise productivity suites. If you just make photos black and white and resize them, you don't need Photoshop to do it. Or even ms paint. Any LLM will make a simple free program with no ads to do it. Average people generally do very simple dumb stuff with the expensive software they buy.
