I think you are majorly overstating OP that ai "didn't work". In fact I agree with the post on almost all aspects and I'd be the last to tell you ai doesn't work. It absolutely does but with a caveat... It's still a tool. And better expertise in the problem domain, along with a better harness used for verifiable outputs will get you better results.

I think the posts mental model of stastically likely prompt completions is spot on.
