That's really going to depend on how strictly you define "vibe coded". If that means that someone put in a single prompt and the LLM spit out an entire program, then yes, I doubt that would be copyrightable.

However, if the person "vibe coding" does understand how to program, and they use multiple prompts and organize the code to make a working product, then the code could be copyrightable by compilation:

That's a real big 'if'. Someone who understands and shapes the code isn't really vibe coding. I might still not agree with what they're doing, but it's not vibe coding if they can take responsibility for every line of code produced.
