Is there more context to this? I'm assuming Ben is experimenting and demonstrating the danger of vibe circuit designing? Mostly because I know he has a ton of experience and I'd expect him to not make this mistake (also seems like he told the AI why it was wrong)
I'm not sure, it was posted on HN a couple weeks ago with the same title as the text in his tweet. I'd guess he was experimenting and trying to show the dangers, like you suggested.
