Claiming that performance is not complicated, as a blanket statement, is absurd.

There are certainly plenty of performance problems that are not complicated, you're correct that many people do not have the skills necessary to solve even simple performance problems. The connection to social intelligence is a leap that doesn't really follow, though; this feels more like you just trying to dump on people who are missing skills, which isn't usually very helpful.

Regardless, however, there are absolutely performance problems that are complicated. When you're trying to optimize performance in environments constrained by compute, network, disk, and memory, finding the right solutions to reach the right optimum amongst the contributing factors can, in fact, be very much nontrivial. This is especially true if you're working on more general systems for which client use patterns may vary wildly.
