A further unpleasant fact of life: biologists have discovered that the more complex a life form is, the quicker it goes extinct. That hapless cream-puff of the animal kingdom, the jellyfish, rather uncomplicated in form and function, has been around for 500 million years and counting. The average kick at the can, for a complex species, lasts four million years, which happens to be about how long we’ve been around.

This is such a wonderful kick in the complacency.
It’s taken me so much effort just to wrap my brain around the reality of the place of a human life [my life!] in the scale of things. In that effort, one thing I was tempted to fall back on was the crutch that at least a human life is part of the Grand Arc of Human History. Meanwhile, we still appear to be alone in the universe, day by day adding weight to the idea that there’s some sort of hard wall faced by intelligence during its evolution.
