it is a task done so fast and effortlessly by the human brain, that we don't even think about it.
It would be more precise to say those are the capabilities of one of the systems that comprise the brain. I think it's a mistake to lump the speed of perception in with the speed of cognition. To put it another way, pointing to the superiority of a gigabit ethernet connection is probably misplaced if it's connected to a microcontroller board running with a 5 MHz clock.
teaching the average person to use a new piece of software is near impossible without utilizing their incredible brain power for visual recognition
This is where I fear GUI enthusiasts often go astray: conflating everyday usage of software with the experience of people learning to use it. It is very useful to examine a light switch when you first encounter it, for example, but people quickly adapt to the common use case of flipping the lights on when entering a room without having to look at the light switch.
