It is honestly amazing to be noticed, even if negatively, by someone of the eminence of Steven Pinker. I respect Pinker because (among other reasons) Steve Sailer, whom I also respect, respects him and has explained in terms I can understand why Pinker’s work is worthy of respect.
Pinker and I have one major disagreement (and I assume many others), which is brought out in his tweet: I have a foreboding sense of apprehension about the future; Pinker by contrast wrote two whole books arguing that now is the greatest time to be alive. What I recall of them is that Pinker’s case centers around, first, a decline in violence. Which I don’t doubt is true in many respects, though as Sailer points out, it can be made easier or harder to argue the world is less violent than it used to be depending on when you start the clock. Second, Pinker enthuses about various advances of science and technology, much of which I would have to concede, especially since I am a beneficiary and consumer of so much of it.
