Renowned physicist Prof Stephen Hawking has said robots will eventually replace humanity COMPLETELY.

Prof Hawking said that he believes artificial intelligence (AI) will eventually reach a level where it will essentially be a "new form of life that will outperform humans", the Cambridge News reports.

He said: "I fear that AI may replace humans altogether.

"If people design computer viruses, someone will design AI that improves and replicates itself.

"This will be a new form of life that outperforms humans."

The professor is also urging young people to be more interested in space - and science in general.
