Agree to disagree. This planet has been shaped and reshaped by cataclysmic events emanating from space...one about 12k years ago probably explains why we know next to nothing about what the other 95% of modern human history outside of recorded history is all about.
Your view that my point is hyperbole comes down to perspective. The same sort of thinking you are employing is why Fukushima happened and why Katrina was such a disaster...an obvious problem wasn't treated as such until it was too late. The one we're talking about just happens to be one we wouldn't recover from. Back to square one and there will be no giants shoulders for people like you and I to perch on.
Laser ships are awesome, space travel is necessary to ultimately avoid extinction...controlling our local environment is also necessary. Being short sighted, even on the millennial scale is irresponsible to the future generations and probable long term achievements we are capable of.
