Very well said dude,
I will add though that, there are some freaks in this world, people that do operate on a whole different level, be it via genetics or just by a mindset that the majority of pedestrians just can't grasp.
These people however are NOT the ones to focus on, simple because that are just that, freaks, and to think that what they can do is attainable by all, well, that is where lots of crap starts to happen.
best to focus on what the "typical" person can do within a given system and now what the "elite" can do, to get a better judgement of the system.
Your point about the whole "effectiveness of the unknown" is a very valid point too, something that still drives many TMA systems.
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
