Author admittedly didn’t know how to scale his app for thousands or hundreds of thousands of users. He jokes about it working great on localhost or “my machine”.

Not knocking the premise of the post. It probably works well for one single user if it’s an iPhone or Android app. But his 100 power hours are probably just right for what he ended up launching as he iterated through the requirements and learned how to set this up through reinforced learning and user feedback.

Yeah but if you have to describe in very much details in english, you're better of just writing it with autocomplete.

I find that vibe coding is useful when it can be build with little details and it makes the right assumptions.
