> if AI saves you time, why wouldn't you use it?

Because generally speaking, stuff that is AI generated is largely devoid of value. If it’s AI generated anyone can prompt it into existence, so the likely hood that someone will find value in and use what you made is approximately zero. What you made is likely low quality, since you vibe coded it with little effort and that always shows. Lastly you don’t even get to experience the joy of solving problems yourself or the pride of having built something with your own skill.

Using some AI to build something is fine, it’s when it’s used so much that it’s immediately obvious on the packaging - the show hn post, the readme, the code itself.
