You can argue that's the point of prototyping. Iterate fast. Getting a "junk" prototype in 2 days is better than getting the same in 2 months.

Now the quality of what comes after the iteration depends on the reviewer, and that's no AI's fault.

Well the worst thing is it allows you to make a really convincing pile of junk and get people to pay for it. Then you can worry about the details when you have your first paying customers.

That's where everyone is overconfident. And that's where mature companies like ours are starting to get customers come back again after jumping ship for some vibe coded startup and getting screwed.

LLMs, minimum advantages aside, are merely amplifiers for the worst characteristics of the human race.
