Are you daft on purpose? He isn't complaining that bots exist or that he refuses to adapt. He's saying some of them have inhuman sight and reflexes that don't feel remotely player-like.
Getting instantly spotted through foliage, smoke, windows, or the second you expose a pixel is not "good positioning advice," it's the exact problem being described. Telling people to use silencers, go prone, or lean peek doesn't address whether the AI reaction time and detection are overtuned.
The point is they should behave within believable player limits, not like they have perfect visual processing and snap reactions.
