AI is seen as a way out of drudgery but you're just trading one problem for another.
Take woodworking for example. When I build a kitchen cabinet, I can get lumber that's already smooth and treated, I can buy drawer tracks, I can use power tools instead of a handsaw and a screwdriver, I can use a pocket hole jig to make joints easier. I still have to do more planning and assembling than with the Ikea cabinet, which also takes more work than having a contractor do everything for me.
I'm doing it my way because it's fun for me. Other people might enjoy other parts of the process - or different things altogether.
There's a whole spectrum between doing everything from scratch and paying someone to have it done for you.
It's actually quite similar to buying the services of a programmer off Upwork to build something for me, only with LLMs it's way cheaper and faster, with a shorter feedback loop.
What do you think architects do? Or interior designers? Or civil engineers?
Architecture certainly isn't building, and neither is interior design. Civil engineers calculate and specify the loads in excruciating detail, because if they didn't, people would die.
You can accomplish most of that by installing Syncthing.
But the objection is that you’re not really building anything new even if you think it’s a new idea. By your definition you’re building for yourself and not sharing…so what good are your little projects. Reading your original list it just seems like you want to build and run software without having to do any research, even if a solution already exists.
