<i>"No [nuclear] bombs have been detonated for 70 years."</i><p>That is wildly inaccurate. At best, no nuclear bombs have been detonated <i>in anger</i> for 70 years.<p>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].<p>If the author is intending to show how a group of dedicated, thoughful scientists can preempt disaster, this was a poor example.<p>[1] <a href="http://nuclearweaponarchive.org/Library/Catalog" rel="nofollow">http://nuclearweaponarchive.org/Library/Catalog</a><p>[2] <a href="https://en.wikipedia.org/wiki/Comprehensive_Nuclear-Test-Ban_Treaty" rel="nofollow">https://en.wikipedia.org/wiki/Comprehensive_Nuclear-Test-Ban...</a><p>[3] <a href="https://www.ctbto.org/nuclear-testing/history-of-nuclear-testing/nuclear-testing-1945-today/" rel="nofollow">https://www.ctbto.org/nuclear-testing/history-of-nuclear-tes...</a><p>EDIT: The article has been corrected.
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.
