Nothing wrong with a professional developer with years of experience using AI as a tool for coding, just as long as they review the output first before using it in their project. My workplace (where I work as a dev) provides us with a Claude subscription to use it as a tool. It's kind of just like using a drill instead of a screwdriver to screw something into a wall - done well in the right hands it's fine, give it to a 13yo and they're going to drive the screw through the plaster and make a holy mess of it.
What IS wrong is a human who has little-to-no experience coding using an AI to develop the entire codebase and then the human releases the code into the wild without some level of peer review from a human who DOES have experience and then claiming it as their own creation. That's almost sloppy plagiarism (of ironically already sloppy plagiarism).
