What do you think about what Stephen Hawking has been saying in reference to the Earth's attempts at contacting intelligent life elsewhere in the universe?

I heard this on the radio yesterday so I looked into it a bit further.

Stephen Hawking says we should be wary of trying to contact other intelligent life in the universe because they’re likely to be more powerful and more intelligent than we are, and may think of us as disposable.

Scary.

A quick Google search brings up a bunch of articles. There’s also a documentary coming out.

Here’s one article. http://www.businessinsider.com/stephen-hawking-finding-aliens-could-be-the-best-or-the-worst-thing-ever-to-happen-to-humanity-2016-11
