I think their point is that you aren't really doing the implementing, Claude (or any model really) is. If you genuinely find prompting LLMs to be fun, then by all means go for it.
What I find fun is getting the output to exactly what I want. I don't care whether I'm personally implementing something or not, and that's what many in this thread seem not to understand.
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?
