> AI placeholders during development as it can majorly speed up/unblock

Zero-effort placeholders have existed for decades without GenAI, and were better at the job. The ideal placeholder gives an idea of what needs to go there, while also being obvious that it needs to be replaced. This [1] is an example of an ideal placeholder, and it was made without GenAI. It's bad, and that's good!

A GenAI placeholder fails at both halves of what a placeholder needs to do. There's no benefit for a placeholder to be good enough to fly under the radar unless you want it to be able to sneak through.
