The article has nothing at all to do with Google.

"No [nuclear] bombs have been detonated for 70 years."

That is wildly inaccurate. At best, no nuclear bombs have been detonated in anger for 70 years.

A nuclear weapon was detonated during nearly every year between 1945 and 1996 [1], when the Comprehensive Nuclear-Test-Ban Treaty was adopted [2], over 2,000 weapons in total. Several nuclear weapons have been detonated since, though the rate has decreased [3].

If the author is intending to show how a group of dedicated, thoughful scientists can preempt disaster, this was a poor example.

EDIT: The article has been corrected.

For these guys rational thinking has become a kind of solipsist secular religion and, like with all religions, its adherents are seriously delusional.

Silicon Valley billionaires have proved repeatedly that they are nothing more than overgrown teenagers. I hope that they do achieve interstellar colonization. This planet will be better without them.
