Ray Kurzweil : The accelerating power of technology

Ray Kurzweil at TED2005  (transcript)
The accelerating power of technology
Summary
We, humans, become tired when we continue doing something, our growth is slow, and we grow little by little every day.
However, by using technology, our work can continue being done without taking a break, and then it's not linear but it becomes exponential.
Exponential is not double, not two times and not three times. It's power, squared, cubed, to the power four and it can be continuing.

Technology can be growing exponential, the power is accelerating and exploding. The first step took ten of thousands of years, for example, stone tools, fire, the Genome Project, the evolution of DNA, the PC, the web, cell phones, the communication revolution, counting, and those are the evolution of our species, though, those will be done in the last few years.
 It means that with working mental models of humans, that are explanations of someone's thought process about how something works in the real world, technology is growing exponential.

However, it doesn't mean that we don't need to do anything or many things that we did were wasted. It's acceleratingly growing with peril.  We have to have the will to apply those to the right problem. I think that especially, the problem of lacking energy is important because people are optimistic.
