Kurzwel wants to show us how significantly shift the world and many issues we have had. He shows why some people make wrong prediction about the future; he says that when people make a prediction about solving a problem, they use the same tools and technology we have today. However, he says we have to consider the changes and the growth in all the part will occur in our prediction.  He gives an example to show what he says; several decades ago, more than 5oo million people were in poverty, but now it is becoming about 200 million. So, technology growth can help us solve many problems like it is mentioned. Also, He talks about how the insisters are becoming smaller and smaller and cheaper at the same time. He believes that nano-engineered designs have a huge significant role in this growth. From his study, he makes some prediction about where technology would be in the next decades
