never heard of this technological singularity, but I've noticed that we get more advanced every year with our technology. Not sure I agree with the definition of the singularity. It seems to me that this singularity is where we stop increasing our technology, but that could be because I'm none too familiar with singularities to begin with.
In other words, I don't see how augmenting or rpelacing the brain is a singularity, because even then our tech knowledge would still increase. The exponential makes sense though. All of history to develop wheel. fourthousand years after that we have plane. 60 years later, we're on the moon. forty years later we're . . . okay, so nothing incredibly new in manned space, but we got awesome computers. next decade, your nanobots.
All a man's knowledge comes from his experiences
