Public Sees a Future Full of Promise and Peril

Imagine a future in which cancer becomes a memory, ordinary people travel in space, and computers carry on conversations like humans. Now imagine a darker future – a world beset by war, rising temperatures and energy shortages, one where the United States faces a terrorist attack with nuclear weapons. 

Most Americans think that these developments and many others are likely to unfold over the next 40 years. In the public's view, this promises to be an era of technological progress. Large majorities expect that computers will be able to carry on conversations (81% say this definitely or probably will happen) and that there will be a cure for cancer (71%). About two-thirds (66%) say that artificial arms and legs will outperform real limbs while 53% envision ordinary people traveling in space. 

At the same time, most say that war, terrorism and environmental catastrophes are at least probable by the year 2050. Nearly six-in-ten (58%) see another world war as definite or probable; 53% say the same about the prospect for a major terrorist attack on the United States involving nuclear weapons. An even higher percentage (72%) anticipates that the world will face a major energy crisis in the next 40 years.
