In some ways, having a superpower is not all that great because then you are forced by the prisoner's dilemma to use it. And if you think about it, it comes at a cost: a higher mental strain over a long period of time.
To use a physical analogy: a workout machine at the gym is very likely to assist you in targeting specific muscles compared to just lifting stuff you need to lift, but it also allows you to push that specific muscle group harder and thus increase the chances of injury to that muscle group precisely because it's so targeted. I think AI is like that with the brain.
(I'll add that it's perfectly possible to work out safely at the gym with lots of equipment. But I've spent years at the gym and I've seen a ton of injuries because the temptation to push a specific muscle group hard is there. And, AI is much worse because with AI, there is an economic incentive to push harder, whereas at the gym it's in your best interest to dial back...only sometimes people like to show off to their gym buddies.)
