Hawking: If Humans Survive a Couple Centuries, We'll Get Off This Rock

He’s not knocking climate scientists’ attempts to figure things out on Earth–he’s just thinking long term. “There have been a number of times in the past when our survival has been touch-and-go,” explains Hawking at Big Think, mentioning the Cuban Missile Crisis, and “the frequency of such occasions is likely to increase in the future…. Our population and our use of the finite resources of the planet earth are growing exponentially along with our technical ability to change the environment for good or ill,” while “our genetic code still caries our selfish and aggressive instincts” [The Atlantic].

Combined with Hawking’s statement earlier this year that it might be dangerous to contact aliens because they could come and wipe us out, the physicist’s latest warning makes it feel like he’s increasingly a member of the gloom-and-doom crowd.
