if the author knows what they're doing and understand the model of the code at least, i don't understand the reason mentioning that it was vibe coded. maybe declaring something is vibe coded removes part of the responsibility nowadays?
HN guidelines say one shouldn't question whether another commenter has read TFA, so I won't do that. But TFA explains exactly why it was vibe coded, and exactly why they're mentioning that it was vibe coded, which is that that was the central point of TFA.
