Ray Kurzweil is a major visionary and forward thinker, but not in that informercial, motivational-speaker kind of way. He's just an incredibly intelligent guy who has the ability to look at the world from outside the mold (or box if you prefer the cliche term). Here is an interview with him that examines what life might be like in the next 20-30 years. I like how the article starts in the present (discussing productivity and job outsourcing) and then slowly progresses into the future. To give you a taste of Mr. Kurzweil's thinking:
"I take 250 supplements a day. I'm really reprogramming my biochemistry. A lot of people think it's good to be natural. I don't think it's good because biological evolution is not on our side. It's in the interest of our species for people past child-rearing age not to stick around, at least in an era of scarcity, and our biological program hasn't changed since we lived in an era of scarcity. We have a lot of outmoded programs in our genes. One says, "Hold on to every calorie because the next hunting season might be fallow." These are all programs that need to be changed. We have a lot of aging processes that really accelerate when we get into our 50s and 60s, and I'm working aggressively to reverse those."

Needless to say the man is brilliant. Computers and technology have allowed us to enhance our knowledge. As a result they have taken a prime spot in many people's lives - we use them for work, learning and personal growth, communication and entertainment. How cool would it be to have the ability to have instant access to the entire English dictionary and be able to perfectly express oneself at any occasion? What about every dictionary out there? Who needs a translator if we inherently understand what someone is saying in a different language? And that is but a grain of sand of what is possible.
I tell ya, if there is any reason to live longer than our one life it would be to see how technology develops and be able to consistently enhance our knowledge and understanding of the world. Long live progress! :)
