Astronomer Royal says humanity will be replaced by AI robots - and aliens already are

ETs will almost certainly be artificially-intelligent robots, predicts the Astronomer Royal, Lord Rees of Ludlow.And it’s likely that sooner or later, we’ll have been replaced by AI robots too.Lord Rees told the Cheltenham Science Festival that mankind would almost certainly be “superseded” by artificially intelligent super-robots within the next millennium.Lord Rees says that the search for extraterrestrial intelligence is likely to turn up something very unlike us.“What will we expect this life to be like?

I think if we were to detect anything . . . it would not be a flesh and blood civilisation like ours, it will be something robotic and electronic.”The robots we’re creating today, Lord Rees said, are the first steps on the road to a civilisation of synthetic AI lifeforms that will last for far longer than humanity ever could.He said: “It is certainly on the cards that after a few centuries more… 1,000 years… we will have been superseded by electronic entities and they will be near immortal and could go on for the rest of the universe’s history.”Lord Rees added that the same process is likely to have already played out on other planets across the galaxy: “[Another inhabited planet] would be likely to be far behind the Earth, with no evidence of intelligence, or far ahead, in which case we would see the remote electronic progeny of some long-dead civilisation.”SETI expert Seth Shostak agrees that any interstellar travellers will have left their biological bodies far behind and the first extraterrestrial entities we meet will be AI-based rather than living beings.Seth told the Daily Star that it's impossible to guess what their motives would be: “Given that they would be more likely to be machines than living beings.
