Some of the dire projections may not occur, but in light of the warnings from our best scientists, it would be beyond irresponsible to take that bet. By badly disrupting that envelop, we “adversely affect every dimension of human well-being that is tied to the environment.” Increased water scarcity facing 1 billion to 2 billion people. In 2004, Swiss Re warned in a report that the costs of natural disasters, aggravated by climate change, threatened to double to $150 billion a year in 10 years. Stern also points to the consequences of climate change on the weight of degrading environmental conditions. To design policies aimed at creating a low-carbon economy, we need to understand first the extent to which global average temperatures can rise without triggering the dangerous consequences of global warming. Both of these questions must be answered based on scientific analysis of historic climate data and projections of future conditions, and state-of-the-art computer models paint a stark picture of what is to come. Moreover, we would incur a very large opportunity cost, having lost out on the chance to become the economic leader in developing alternative and more efficient uses of energy. Alert pundits now foresee a world saturated with powerful computer chips, which will increasingly insinuate the themselves into our gadgets, dwellings, apparel and even our bodies. But that kind of automation is a far cry from the versatile, mobile, autonomous creations that so many scientists and engineers have hoped for. In light of what I have just described as a history of largely unfulfilled goals in robotics, why do I believe that rapid progress and stunning accomplishments are in the offing? In absolute terms, it’s not so amazing: they calculate at rate perhaps 100 times that of the average person. Implicit in my assertion that computers will eventually be capable of the same kind of perception, cognition and thought as humans is the idea that a sufficiently advanced and sop
