I agree the original author's post is better than this. I think the point I'm trying to make is that "vibecoded" landing pages can actually be quite high quality these days, and the author was sandbagging a bit for their point that 0->1 results are bad (which fair, I'm guilty of the same).
They are correct though that these days you can navigate away from the slop pages that gpt 5 put out pretty effectively, and land on something that really is quite decent. The page I made is a great starting point for 60s of effort on my part.
