it's gonna be an interesting century ahead. John Von Neumann talked about a singularity occurring which "centered on the ever accelerating progress of technology and changes in the mode of human life, which gives the appearance of approaching some essential singularity in the history of the race beyond which human affairs, as we know them, could not continue." It's become a major theme with futurists since then.
The concept makes sense to me. In other words, something's gotta give. I truly want to be optimistic about humanities future though the road leading us towards the transition will no doubt be bumpy and inequitable. Either we reach a point where further advances in technology become impossible because as a civilization we are unable to wield them or we transcend into something all together new. Basically, human evolution has to keep pace with technology, and like it or not we're going to have to find out if we're ready.
calling it a singularity might be romanticizing it cause singularities probably appear discontinuous only in hindsight as a breaking of old trends. If Foreigner is right about achieving fusion in about 30 years, which could happen, we might be a Kardashev type 1 civilization by the end of the century ("A civilization with an energy capability equivalent to the solar insolation on Earth, between 10^16 and 10^17 watts.") That's probably optimistic though. It's symbolically a significant milestone because we'd begin to break the chains the food chain has held on humanity for survival. Hopefully through all that cumulative history of human exploitation we emerge a race of people that aren't total assholes.
