Let any who read this be aware: You should be immediately suspicious of AI code that is much much faster than established code bases. AIs are even better at benchmarkmaxxing than humans are, and humans were already pretty good.

It is by no means impossible for an AI-written code base to be faster than a conventionally-written one, of course. It's just a time to be suspicious. Especially if there's little to no evidence that the human has subjected the code base to any further testing of their own. AIs seen to be able to benchmarkmax even in the presence of a lot of unit tests that would generally speaking have prevented a human from going too far down that road.

I am getting increasing disillusioned by the number of peers I am seeing completely hand over their thinking to a tool. Agents are great, but if you can't explain to me how your PR changes a system and why design choices were made you are no longer an engineer.
