Humans would be replaced by robots in coming few hundred years, says Astronomer Royal Lord Rees. Life on earth has been evolved 4 billions of years ago from proteins and nucleic acids that are building blocks of our life. In few centuries machines will take over the entire earth. It will dominate human which would be a small transitional phase.
Emeritus Professor of Cosmology and Astrophysics at the University of Cambridge, Lord Rees said within the next 10 or 20 years we could expect to have technology that will allow us to search for alien life. “My guess is that if we do detect an alien intelligence, it will be nothing like us. It will be some sort of electronic entity,” he further said.
According to Sir Martin, life of a human on Earth is nothing more than a brief transitional phase between early life and the long era of the machines which he’s dubbed a ‘post-human’ future. “Such civilisations would evolve at different rates, hence, it’s extremely unlikely that we will find intelligent life at the same stage of development as us. “More likely, that life will still be either far simpler or an already fully electronic intelligence.”
The Cambridge professor emeritus believes that while we may be able to peer further out into space, travelling to distant worlds will remain out of our reach until we enter the post-human era. In his interview with The Conversation, he added: “The journey times are just too great for mortal minds and bodies. If you’re immortal, however, these distances become far less daunting. The further would be made by a robot and not by us.”
