My take on vibe coding for PMs

I shared this internally at Meta in response to a deluge of clout-chasing posts celebrating PMs landing prod diffs. The response was positive and the message generalizes, so here we are on the open www. If the feature is actually important, fix the system for prioritization (your real job) rather than circumventing it. It is very easy to accumulate tech debt with random PM pet features. ...
