even when Nikon says it about the autofocus system that their engineers designed and built?

I know you questioned my reading comprehension, but aparently it is you that has the problem - so just in case you missed it - this is the quote from nikon when flat out asked if an f/1.4 or f/2.8 lens would autofocus better on a nikon camera than an f/5.6 lens:

"Sure, a fast lens lets more light in to the AF system which allows it to work more effectively and thus acquire and lock focus faster."

aparently you think technology cant advance beyond your symplistic understanding of it - - - what a loser

I am just against people making a technical argument ('the AF is faster because the lens lets in more light') if they do not understand the technology.
