I was debating this issue with a friend, who is still in, but partially awake. He said that there has never been a time like now, where humans have the technology to wipe themselves off the planet. In fact, humans have built enough bombs to destroy the planet itself. He believes the last days began when the atomic bomb was born. There really wasn't much I could say for a rebuttal. He had a good point.
I don't believe in there being any "last days" in the biblical sense, but I can tell you that having NK, China and Russia for neighbors doesn't make me feel safe. Living in a country that was nuked twice and had a nuclear reactor leak from a tsunami doesn't make me feel like this is the safest time in the history of humanity. I haven't read Stephen Pinker's book yet, but I wonder how he feels about nuclear weapons and chemical/biological/drone warfare technology.
