Since humanity will only continue to progress, it’s important that we stay aware of the dangers of our advancements in science and technology, Hawking says.
By the time there’s a major global disaster on Earth, we may already be safe in space.
But we should still try to do everything we can do avoid these threats, since we probably won’t establish self-sustaining colonies for another hundred years.
“We are not going to stop making progress, or reverse it, so we have to recognize the dangers and control them,” Hawking said. “I’m an optimist, and I believe we can.”
