> If the Ai came back to me with a 1600x improvement (still in pgrust readme), I would be highly suspicious of the Ai and the code it wrote

Depends on who wrote the original code. With postgres its sus, but if it's another AI...I wouldn't be surprised. I also saw code writtem by humans that is a result of "I can't figure out how to make this safe and concurrent, so imma just place giant mutex here", and it like 100 lines change to fix that.
