“The heavens were all on fire; the earth did tremble.”
Henry IV, Part 1
For much of my life, I thought our species would soon go extinct. I assumed we might last another hundred years if we were lucky. Now I suspect we are facing extinction in the near future. Can I speculate as to exactly when that might happen? Of course not. My sense of this is based only on probability. It might be similar to hearing about a diagnosis of late stage pancreatic cancer. Is it definite that the person is going to die soon? No, not definite. Is it highly probable? Yes, one would be wise to face the likelihood and put one’s affairs in order.
