Scientists: Humans and machines will merge in future

"We want to preserve the best of what it is to be human and maybe even amplify that," Bostrom told CNN.

Transhumanists, according to Bostrom, anticipate a coming era where biotechnology, molecular nanotechnologies, artificial intelligence and other new types of cognitive tools will be used to amplify our intellectual capacity, improve our physical capabilities and even enhance our emotional well-being.

The end result would be a new form of "posthuman" life with beings that possess qualities and skills so exceedingly advanced they no longer can be classified simply as humans.

"We will begin to use science and technology not just to manage the world around us but to manage our own human biology as well," Bostrom told CNN. "The changes will be faster and more profound than the very, very slow changes that would occur over tens of thousands of years as a result of natural selection and biological evolution."
