Is it really necessary for humans to live in space in the next 1,000 years as Hawking said?

Hawking said this not without reason. In Hawking's speech quoted by CNN, he gave an example of a series of events that may cause human extinction. For example, climate change, exhaustion of various resources, rebellion by artificial intelligence, nuclear war, etc.

So Hawking warned us that if we want to survive, "our best chance must be to leave the earth we are familiar with and establish colonies on other planets."

Hawking predicts that mankind may encounter crises in the future

But at the same time, Hawking expressed a certain degree of optimism about the prospects of mankind in recent decades. He said: "Although the earth will not be stable for some time in the future, The possibility of facing a devastating crisis is not high,

But as time goes by, the crisis for mankind will become closer and closer. In 1,000 or 10,000 years, the occurrence of the crisis is certain. Hawking added: "It's really time for us to run towards the stars and the sea. The disaster on the earth will not become the end of mankind."
