I'm pretty sure a large fraction of the vibecoded stuff out there is from the "ideas guys." This time will be different because they'll find out very quickly whether their ideas are worth anything. The term "slop" substantially applies to the ideas themselves.

I don't think there will be copyright or patents on prompts per se, but I do think patents will become a lot more popular. With AI rewriting entire projects and products from scratch, copyright for software is meaningless, so patents are one of the very few moats left. Probably the only moat for the little guys.
