I am referring to hardware errors.
CPUs making errors. The ratio of errors is known to the manufacturers, and they adapt, trying to minimize the effects of the errors by way of firmware and redundancies and whatnot.
But someone at Intel or AMD can tell you whether I've understood it wrong or not.
Now the human brain, that's a thing with an enormous tolerance for misfires. A CPU has less misfires, but less tolerance too, since it trusts itself more.
