alt Hacker NewsNothing 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.
