Radical Evolution Chap.3&4

In chapter 3, "The Curve", indicates that "the power of information technology will double every 18 months, for as far as the eye can see". Somehow, I got scared when I read this. I think it is because I felt some possibilities that information technology might exceed human brain sooner or later. After all, I've come to a question. Does the development of technology have a limit like other sources such as fossil fuels? Why technologies can be developed so much?
On page 53, it says that computers and technologies will do all the jobs for us. However, if it actually happened, people would lose their jobs and economy would go down. The people who are experts of technology would survive and others would suffer from poverty. Therefore, we need to put a certain limit on the development of technology in order to keep the economy stable.
Also, I think the current situation that some people cannot live without computers is a significant problem. Human beings are already relying on technology and some people feel fear without it. It could be said that the world of human are getting invaded by technology, which is very sad.

In chapter 4, The Heaven, shows that how the development of technology could benefit our world. On this chapter, the advantages of radical evolution are listed. The conclusion of this list is: "The twenty-first century could end in world peace, universal prosperity, and evolution to a higher level of compassion and accomplishment". I strongly thought "can we actually realize all of these?!", especially the world peace is very difficult to realize. It means that by the end of this century, all people in the world have to be able to know how to use technology. But, wait a minute, before spreading all the skill of technology to realize the will, we have to consider how to stop the poverty, and reduce the gap between developed and developing countries.
In the end of this chapter, Kurzweil, predictor, says people could be God-like in the future. However, I thought that why we need to be God-like? What is the purpose of us developing technology? To be a God? To be alive forever?

I strongly felt that "what is the last purpose of doing this?" The purpose is no longer to make our life convenient.
