<p>> <i>subsonic lift is well understood and has been for decades</i><p>I said easy. Not well understood. I can fly planes. It’s hard, and has limited room for fucking up. (It’s also hyperbole to suggest we understand lift. We don’t.)<p>Piloting a boat is easier and more forgiving. Hence, splashdown. You don’t need direction. You don’t need lift. Parachute physics is a backbreaker, but it’s symmetrical. Same for splash.</p>

<p>I think the difference is extermination from an area versus exterminating a line. Humans and chimpanzees will exceed their territory to eradicate foes. That, per this primatologist, is a unique adaptation.</p>

<p>> <i>he literally just posted a video on his account of a woman being violently beaten to death with a hammer as a call for people to do something about immigrants</i><p>Zero dispute. I’m challenging the notion that Americans are rising to that call. (Or cheering on specific attacks, versus general notions of violence.)<p>In a weird way, maybe social media helps in this one instance. We can’t let the enemy be faceless. There is no glory in shooting a specific mother or nurse.</p>

<p>> <i>war crimes blew the Overton window for violence wide open</i><p>I see no evidence of this. We didn’t see it after Iraq. And Luigi predates all this.<p>These aren’t organized political movements. They’re lone actors reaching breaking points. That don’t need a theory of violence, just access to guns and a day of mental instability.</p>

<p>I’m trying to find the source, but I remember a primatologist claiming that humans and chimpanzees are the only two species that embark on genocide. Not being satisfied with simply defeating the enemy, but actively hunting them down to ensure they can’t harm you again. In other words, precluding retreat. (Which creates its own game-theoretical backlash: never retreat.)</p>

<p>> <i>Do you spend much time with people not in the tech world?</i><p>Most of it. Across the political spectrum.<p>> <i>even if not to such an extreme</i><p>That’s precisely the point. There is a massive difference between doing or aiding and abetting such behavior, cheering it on, and giving into the impulse of “couldn’t have happened to a worse person” before self correcting. There are a few saints who reject the violence at first glance. But most people are in that self correcting phase, and the correction happens the more they learn about the specifics of the assault.<p>> <i>even the president regularly calls for and promotes violence</i><p>To what numerical end?</p>
