While science and technology have the potential to create an ideal habitat for humanity over the next millennium, there is the possibility of a monumental genetic hangover over the subsequent millennia due to an over-reliance on technology reducing our natural capacity to resist disease, or our evolved ability to get along with each other. After that, things could get ugly, with the possible emergence of genetic 'haves' and 'have-nots'.
Seriously, leaving aside the genetic angle, technology is already rapidly creating an even greater divide within humanity - those who have it and understand how to use it, and those who do not. A divide may be coming - faster than we think - where the former group begin to merge in a meaningful way with their technology, and leave the latter group well behind... at which point the world becomes a vastly different place.
That I-Pod of yours, or that cell phone, or Blackberry, or X-Box 360, or ___________________ (fill in the blank) is taking us further and further away from the rest of the human race, bit by bit, at an ever accelerating rate. I'm not suggesting that we should give them up - rather than slowing ourselves down, we should be working harder to make sure that everyone else keeps up. Most of all, in our rush to have all of the latest gadgets, including those that may become part of our own bodies, we must not forget those who don't have access to them.
The alternative to maintaining an awareness of the growing divide within humanity, and trying to do something about it, is a bleak future for us all.
