I fear the future. I fear the things that will be required of us will be so far beyond our capabilities to cope with it that we will be overwhelmed. Is there going to be any life on Earth by 2050?
If everything ends more completely than the Book of Revelations suggests it will, then we will have to be satisfied that life on Earth was a beautiful thing while it lasted. And the universe as a whole is better off than it would have been if we never existed.
And I am only a simple school teacher that used to yell at seventh graders. So, I could be wrong, and life will find a way.
