I'm with you. I've done some pretty special things over the years I was employed, none of which had any input from LLMs. Now I'm retired and I have a tool at my fingertips that I can instruct, manage, and (sometimes eventually) get what I want. It's not massively dissimilar to managing a group of engineers...

The inspiration, the ideas, the workflow, the vision, the end product - all mine. The grunt work that takes all the time - hand it off to the LLM, and make sure it bloody works at the end.

With that approach, I built a compiler for my own language - it runs on {Mac, Linux, Windows} and any of those can produce code for {Mac, Linux, Windows, WASM, iOS, Android, Zynq, m68k, 6502} - the last 3 being more useful to me than most people I expect. I have a signed binary running on my phone, which was developed on a Linux box and never saw anything from an Apple Xcode installation...

That compiler was how I (and Claude) wrote a WASM client to a server back end, all of which use the exact same classes and data formats, making integration trivial.

I'm working on a cross-platform UI framework now, with a Cocoa-like UI description, that you drag lines between your code and the various UI platforms you want to support {Desktop, tablet, phone}, with mobile variants offering portrait and landscape. Write your actual program logic once, and visually connect UI into it, on a target-by-target basis. Support any platform with one codebase.

I wouldn't have considered taking on a program of this complexity without the LLM. It'd just have been a pipe-dream. They're tools. Wonderful tools, but still tools.
