you know, there's a certain balance in nature. if you die, you become food for the most primitive form of living, and the food chain begins anew. it's a cycle; in fact most natural things are cyclic.
in the same way progress wasn't made entirely by NTs, because those same NTs wouldn't be able to progress without NFs. it wasn't a rational that walked out of the caves when our species were still infant - it was an idealist. but it was the rational who built the first hut/house.
even though this is just a minor point, it is worth mentioning that we wouldn't be this far without either N types.

from the day i sat down with a friend and deducted the meaning of life (it's not a big deal, honestly), i have had a different view of progress. nature does not care about who lives or who dies, nature does not care what happens to entire planets, systems or galaxies. in the same way, nature does not care who progresses or not. we make our own goals to see and understand the universe, nature and everything within, because that's how we were created (i do not take this point for granted, but i don't want to elaborate upon it now).
it is only recently (~2500 years ago) we have thought that the perception and conception of the human mind may be limited in searching for the truth of reality. and it is only by the advancement of present day neuro-scientists that we may actually be able to go beyond the perspective of the human mind. to do this, of course, we need to disassociate ourselves with being human.
progress does not necessarily mean extinction. progress merely means that in order to get an objective view, to see "the truth", we need to go beyond humanity; and not just humanity, but to go beyond any species of atom based material. if this means extinction for a race or a species, well, it'd be a small price to pay to become all.
i consider it the price even smaller due to that the number of atoms will stay the same - they will just be relocated. new species will arise as the deaths of more primitive ones are carried out. if anything, this displays a greater cycle of life; and that progress is merely a part of this cycle. we are not the end; we are means to an end. and with that end, a new beginning will come that may just bring us a little step closer to understanding nature.
as an additional note, i realize that this is perhaps the greatest overview the human mind can have, because this is what we're striving towards. in this overview, elements such as education, resources and so on become irrelevant. whatever obstacle will come, there will always be someone who will be able to circumvent it in the quest for this, shall we say, ultimate goal?
