I have never had my ID checked at the gate on a domestic flight, only by TSA at security or at the ticketing counter when checking bags.

This is discussed at length in the article, so I'm surprised to see this top of the comment page. I suppose it flatters HN readers' view of themselves as smarter than journalists.
> “Upper room” UV, the primary form of UV disease control tested to date, is a kind of compromise. The primary wavelength it uses, 254 nanometers, is dangerous to human skin and eyes if directly blasted at them. So, well, you don’t blast it directly at them. The next best thing is to put the lamps high up in a room, where they can kill pathogens at that height and spare the humans.
> The problem is that you can’t safely shine conventional 254 nm light at humans, much less at the wounds of humans who are recuperating from surgery. So Brenner and his colleagues, thinking about the donor’s challenge, arrived at the idea of trying out shorter wavelengths, 207 nm or 222 nm far-UV. Those wavelengths penetrate far less than conventional UV, and because of that, far-UV seemed much less likely to damage human skin or eye cells, while still being strong enough to kill viruses and bacteria.

It might still be possible to interfere with those, but it's much more difficult than electronic voting machines, which can in some cases be manipulated over the internet, or very quickly by a voter who exchanges memory storage units.
This goes into more detail - yes, in some states it is illegal for teens to possess tobacco, but the penalty is usually something like a small fine, or you have to attend a class.
It's also irrelevant to the MRCA of extant humans.
Neither is useful to the novice, but an article like this going out of its way to explain, say, matrix notation, or a video about building chairs that spends the first ten minutes explaining how to use a table saw, is less useful and interesting to the experienced reader or viewer.
I suppose I agree that articles like this shouldn't be presented as easy, or for the beginner, but there's a difference between "simple" and "easy".
Perhaps there's a case to be made for exposing people to controversial or offensive ideas in a controlled environment to prepare for encountering them in an uncontrolled environment - in fact, this is frequently called a "safe space" and ridiculed by people who believe that modern societies are too "snow-flakey"!
But that's certainly not what internet trolls are doing.
The TSA wants to externalize its discrimination to "the machine", but the machine is a product of human systems, and reflects and captures the biases that already exist in society.
The average driver files a claim for collision once every 17.9 years [2].
That makes human drivers 16 times safer than Uber self-driving cars. This is concerning for people who think self-driving cars are right around the corner! Improved algorithms would need to avoid 94% of the collisions that self-driving cars currently get into in order to have the same failure rate as humans.

*actually, it's not impossible, since you could have a child transmit DNA horizontally to its parent, but this would in reality happen over a sufficiently short timescale that you wouldn't see it on a phylogenetic tree.
I also don't quite understand what you mean when you say that the Founding Fathers didn't establish an aristocracy of their own: the first five presidents were involved with writing the Constitution and establishing the Federal government, and the sixth president was one of their sons!
