It's just that we really don't pay attention to the earth not being destroyed by a meteor today.
In most of the rest of the world it might be even worse. Especially if you also consider the size of countries like India and China. Most countries have only had peace for less than a century. New technologies end up abusing, if not killing, hundreds of thousands of people. The global economy seem to experience one large crash every decade. A lot of things are getting better, but I certainly wouldn't say the are getting more functional. I would even say that a lot of development is more unsustainable today than ever.
When a million people don't die in traffic every year I will get more hopeful about humanities ability to handle existential threats. Until then let's hope for a something smaller event first (I don't really know the distribution of something like a meteor).
Any preventable scenario requires people ignoring it to happen. Which I guess in itself isn't very helpful. It is just that people tend to assume that dysfunction isn't normal when it is usually the opposite. That anything functional often requires long deliberate and concerted efforts. There are for instance still plenty of people dying in traffic.
