40% of Americans say Jesus will come back by 2050

Americans are largely optimistic about the future, according to the poll from the Pew Research Center For The People and The Press/Smithsonian Magazine.

By mid century, 71 per cent believe cancer will be cured, 66 per cent say artificial limbs will work better than real ones and 81 per cent believe computers will be able to converse like humans.

But Americans are also braced for a major energy crisis and a warming planet, according to the survey. More than half, or 58 per cent, fear another world war in the next 40 years and 53 per cent expect a terrorist attack against the United States using a nuclear weapon.
