TED talks are how Silicon Valley markets it's soft side and tried to convince people their intrusive technology is for our own good. For me, it's interesting hi-tech propaganda from people who genuinely believe their BS [will make them obscenely rich]. They like to think that just because their inventions don't produce any nasty physical by-products - any waste, like smoke - that they are off-the-hook and not responsible for the behaviors that their products stimulate. This is uncharted territory for fans of product-safety with almost no legal framework.
Ray is another inventor/futurist who thinks science is the key to our evolution as a species, more than it is the key to our self-destruction. I disagree with him 100%, and understand from his writings that he would like to see a 'enhanced' species of half-android proto-human evolve as our future salvation. (I believe he thinks this will start to happen by around 2050)
Methinks that is no longer a 'human' species, but something quite different and dangerous to actual "Humans" and our traditional view of the world. (Maybe "equality" is something we can never allow ourselves to accept. The ego is a powerful thing. It makes us think we're the only living thing that matters on this earth - but I digress)
I'd speculate that the rush to get into space is an effort to combat the ultimate overpopulation that is expected as life expectancy extends. What is also interesting to figure into that scheme is the lowered birth rates in highly developed countries, and the introduction of job-destroying robots and AI.
So as we get more technologically advanced, we tend to live longer, to want to move to new planets and to breed less. I'm not sure where that leaves the Earth, and humanity, in 150 years. I wonder whether we will learn how to share the resources that we have, or whether our civilization/species will bifurcate into a few technologically advanced haves who can 'escape' to new habitable planets, and mobs of bereft have-nots who are forced to stay here on a ruined and over-exploited earth - this seems like a more natural 'human' outcome based on our historical behavior.
Of course, if we can't learn to get along as a species, this will all just lead to disaster - as all previous human civilizations have encountered. Unfortunately, this would seem to be the more likely path we've chosen...crabs in a bucket.
Happy Friday!
