If I Can't See the World, Does it Disappear?

Well, it appears that that's what Ted Turner believes. In a recent interview, Ted posited that humanity will end in 50 years.

I think Ted is confusing not being alive in 50 years with humanity ending in 50 years. Just because Ted might no longer be around, does not mean that humanity will end. It's like a great philosophical debate - if Ted can't see it, does the world not exist?
