Why not? (Other than they don't currently exist). I would absolutely get a robo-plumber. I have other tools for fixing things around the house. LLMs are just tools.
I think the issue is when you claim to have _done_ something yourself when in fact you didn’t. I think people have trouble differentiating real value vs what they think of as some flavor of carpetbagging
Talented creators have hated poseurs since time immemorial.
I think the issue is that it's gotten far easier to be a poseur than ever before.
Nothing wrong with getting a robot plumber, I would do it too. But I wouldn't go around doing all my friend's plumbing and/or completely redo all of the plumbing in my home with it and then call myself a plumber (notwithstanding that plumbers are licensed professionals).
You've changed the hypothetical there. Calling yourself a vibe plumber and calling yourself a plumber seem like very different things.
