Like Lego, assembly can be fun too, and I don't have to manufacture the individual bricks from scratch just to enjoy assembling them together. But no one doesn't call that building something, similar to your experience.
Help me out with the metaphor here. Do you think designing and architecting some software, then getting an LLM to write a lot of the code, is the same as buying a computer program from a store?
It really depends how you use it. There's a whole spectrum from "do it yourself" to "get the AI to do everything". Its up to each person, on each project, to decide what amongst all of that work is actually worth human time.
I don't enjoy CSS, so I delegate that to an LLM. Just like I don't like writing assembly by hand, so I delegate that to a compiler. So what?
