Well, if you want to use that stuff for your personal use that's totally fine. But there is a difference between doing that and selling your creation as a product. To pick up on your example, it's great if someone learns woodworking and puts together a table or something. You probably won't sell it though because unless you get really good at it, the piece of furniture will not meet the standards for a good product. It's absolutely the same when using LLMs to put together a piece of software. It will fall apart quickly unless you put some serious work in it. A lot of people think LLMs are a shortcut to learning this stuff and then go on and pretend to be professional software developers. I also doubt these vibecoders learn a lot about about coding when they don't even understand what the LLM is putting together for them as a result of a few wishful prompts.
