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.
The biggest value proposition of an LLM is being able to focus on the truly high-value activities while allowing the machine take care of much of that reification.
That you think architecture or interior design isn't building tells you prefer to downplay or devalue any work that isn't hands on construction. It's an interesting perspective, but it's one I'll never be able to understand or agree with.
