An interesting interview with Andy Weir.
The initial windstorm (or, rather, its effects) did seem a little implausible to me, but otherwise (as noted) the book holds up very well, scientifically.

…has been canceled.
Good.
Why economists don’t reach agreement.
Dennis Wingo has a long essay on the history of the US space program, and how we got so far off track. I discuss this quite a bit in the book, but much more in the new one in work.
Kyle Smith liked it.
Its success will really piss off the Hollywood Left, after all their box-office bombs, after which they said Americans “just don’t like movies about the war.” No, they just don’t like anti-American movies.

You know what we called “free range” kids when I was a kid? Kids. I walked to and from school, half a mile away, every day, from the age of seven or so.
[Saturday-morning update]
The overprotected kid:
Sandseter began observing and interviewing children on playgrounds in Norway. In 2011, she published her results in a paper called “Children’s Risky Play From an Evolutionary Perspective: The Anti-Phobic Effects of Thrilling Experiences.” Children, she concluded, have a sensory need to taste danger and excitement; this doesn’t mean that what they do has to actually be dangerous, only that they feel they are taking a great risk. That scares them, but then they overcome the fear. In the paper, Sandseter identifies six kinds of risky play: (1) Exploring heights, or getting the “bird’s perspective,” as she calls it—“high enough to evoke the sensation of fear.” (2) Handling dangerous tools—using sharp scissors or knives, or heavy hammers that at first seem unmanageable but that kids learn to master. (3) Being near dangerous elements—playing near vast bodies of water, or near a fire, so kids are aware that there is danger nearby. (4) Rough-and-tumble play—wrestling, play-fighting—so kids learn to negotiate aggression and cooperation. (5) Speed—cycling or skiing at a pace that feels too fast. (6) Exploring on one’s own.
This last one Sandseter describes as “the most important for the children.” She told me, “When they are left alone and can take full responsibility for their actions, and the consequences of their decisions, it’s a thrilling experience.”
To gauge the effects of losing these experiences, Sandseter turns to evolutionary psychology. Children are born with the instinct to take risks in play, because historically, learning to negotiate risk has been crucial to survival; in another era, they would have had to learn to run from some danger, defend themselves from others, be independent. Even today, growing up is a process of managing fears and learning to arrive at sound decisions. By engaging in risky play, children are effectively subjecting themselves to a form of exposure therapy, in which they force themselves to do the thing they’re afraid of in order to overcome their fear. But if they never go through that process, the fear can turn into a phobia. Paradoxically, Sandseter writes, “our fear of children being harmed,” mostly in minor ways, “may result in more fearful children and increased levels of psychopathology.” She cites a study showing that children who injured themselves falling from heights when they were between 5 and 9 years old are less likely to be afraid of heights at age 18. “Risky play with great heights will provide a desensitizing or habituating experience,” she writes.
Instead, we’re infantilizing them into what should be adulthood (the “keep your ‘child’ on your health insurance until age 26” is part of this). Another aspect of this is all the allergies that people are having as adults, due to being overprotected from germs as children. And the worst thing about all this, as she notes, is that it hasn’t even reduced risk (gee, where have we heard that before?). Anyway, it’s long, but read the whole thing.

“I let my nine-year-old son ride the subway alone, and got called the ‘worlds worst mom.’”

I’d never really read this before, but it’s an interesting description of the rules there. No home cooking allowed, and alcohol is rationed, which makes sense, I guess. I wonder if some people make their own hooch, though?
A lot of interesting discussion in comments. I agree that the biggest difference between this and previous LEO satellite concepts is that he’s solved the launch cost problem, or probably will have when he starts to get them to orbit.
…like it’s 1939. The parallels are disturbing.
Now they plan to tell us not to eat lean meat.
