Cheery Thought
A cheery thought for Valentine's Day:
This planet has been around for 4 billion years, intelligent life for perhaps 200,000, weapons of mass destruction for less than 100. A hundred -- in the eye of the universe, less than a blink. And yet we already find ourselves on the brink. What are the odds that our species will manage to contain this awful knowledge without self-destruction -- not for a billion years or a million or even a thousand, but just through the lifetime of our children?
