I think it's obviously important to separate on one hand talking about things like the potentially massive benefits of technology, reaching a critical mass, etc, and on the other hand taking these things to justify laziness until they come to pass.
Also I'm unaware that taking these things to justify laziness is as widespread a phenomena as you all seem to be suggesting. Maybe it's bigger than I though though, it's possible.
Anyways, I think it's obvious that technology can brings us tremendous advantages in the future, and I do believe that a critical mass of enlightenment is a possibility for the future, but I don't condone laziness so I think it's important to make this distinction.
This being said, on a personal level I'm not convinced more technology is the way to go, although I'm leaning in that direction. The thing is it would be such a pain to maintain and to have to always teach new generations about it, because it's so far from nature, it's really not pleasant to deal with at all. In my mind either some of the population would have to make a sacrifice and do it for the rest or perhaps we could all take turns, or alternatively I think it's definitely possible certain types of people would actually enjoy dealing with science and mathematics and technology enough that they would volunteer to take care of it happily (I recognize there are a variety of personality archetypes other than my own).
Also on the issue of a critical mass of enlightenment, again my view isn't black and white. For one thing, enlightenment that would reach a critical mass would have to be of a right-leaning, faith-based variety because it's much easier to learn and teach, and I'm not convinced this is possible or even an ideal goal to strive for. In my view the right-hand path is useful in times of difficulty, for example the slave with no prospects of escape can take far more solace in the notion of God than in the notion of one day himself becoming a master of slaves, and so his faith can give him strength to carry on. The extent to which I see the right-hand path as a vehicle for serious change against very repressive forces is a matter I'm not decided on yet.
