As long as

a) population increases, and

b) humans exhale CO2

we're eventually doomed without some clever engineering.

Which may be why SETI has been such a bust; perhaps it's part of the natural cycle of things that species discover fossil fuel, have an industrial revolution, and then blink out of existence in a puff of greenhouse gasses.

Yes, the dollar will gigalapse, just like the Internet did.

Just like computers will all stop working on 1/1/2000, airplanes will fall from the sky, nuke plants will explode.

Just like 9/11 was a hoax. It was all done by the NSA. With holograms.

Just like JFK was killed by the trilateral commission, in concert with the greys.

Just like Ron Paul isn't an ignorant wacko.

I want to believe.
