> The brain has infinite potentials
No, it doesn't. The brain has a finite number of possible states to be in. It's an absurdly large amount of states, but it is finite. And, out of those absurd but finite number of possible states, only a tiny fraction correspond to possible states potentially reachable by a functioning brain. The rest of them are noise.
You are wrong! Confidently wrong at that. Distribution of potential, not number of available states. Brain capacity and capability is scalar and can retune itself at the most fundamental levels.
