Joel Mokyr, distinguished professor of economics and history at Northwestern, is optimistic, and I agree:

Certainly, it is difficult to know exactly in which direction technological change will move and how significant it will be. Much as in evolutionary biology, all we know is history. Yet something can be learned from the past, and it tells us that such pessimism is mistaken. The future of technology is likely to be bright.
