Border agents have been able to conduct searches of persons and their effects entering the country since the first Congress in 1789.

First, searches of their persons and effects does not mean reading and making a copy of their letters and books. It means looking in the trunk and verifying that it is just letters and books.

Second, there were no border agents in 1789. You could walk or swim into the U.S. from Canada and Mexico freely for (statistically) most our nation's history. The first border patrols began in the 1920s to restrict immigration from certain countries. There were laws in the late 1700s regarding import of *cargo*, and that was handled by the folks who ran each individual port, but again, that's not the same thing as searching a passenger's person and making copies of their letters. Those laws applied only to identifying goods that were likely intended for sale, for tax policy/import duty reasons.

This bastardization of border policy to include searching the contents of people's papers and devices is a late 1900s perversion of the Constitution.

So no, pretty much everything you said is wrong.

But you simply can't rely on homework scores to be a proxy of learning or time spent studying anymore.

You never could. Parents do their kids' homework all the time, or siblings, or friends.

Homework used to be a measure for yourself to indicate whether or not you really understood the concepts being taught. Math is a prime example here. If you found your homework speed accelerating with confidence as you worked through problems correctly and accurately, it was a pretty good indicator of how you would perform on a test.**

It still is if you do it yourself and don't have ChatGPT do it for you. But it isn't a useful indication for parents or teachers, because the kids can just have ChatGPT do it for them, and moreover are encouraged to do so by the pressure to get good grades. By making the homework be graded only on adequate participation (which may be per-student) rather than on correctness, you shift the focus back to the homework being a way for students to get ready for the test and make it clear that having an AI do the work will prevent the teacher from knowing how well the student is doing, and will likely result in a lower grade on the test. Once the motivating factor of grades is eliminated and, in fact, reversed, they'll stop doing it, or will use it only to help them understand or to check their work, rather than using it as a crutch to actually do the work.

Ideally, teachers should give a large pile of optional homework.

For those students gifted with high motivation, they already recognize the value of optional homework that exists today. Any child gifted with high motivation wants to practice more, and is likely being raised by a parent who is more than capable of presenting those challenges. And does.

Any child gifted with high motivation and broad interests wants to practice stuff they already understand less so that they can do other things and learn other things. A child's time is a zero-sum game. The more time they spend doing things that are less useful, the less time they have for doing things that are more useful.

The ones who mindlessly work more problems because they are motivated to get good grades are the ones who aren't doing band, orchestra, chorus, or theater, who aren't going on field trips to learn about the world, who aren't getting the breadth of education that will prepare them for the real world, and will mostly end up in boring (but probably reasonably well-paying) jobs for the rest of their lives. They won't ever be the rockstar in their field, but they probably won't fail horribly. And I guess that's okay, but IMO it's not what we should try to inspire kids to become. The motivation should be to learn for learning's sake, and excess repetition is the opposite of that.

This is unfortunately no longer a valid measure because testing has become an exercise in psychological coddling. With time limits, bright lights, and the concept of failing, removed.

Meh. If that's your experience, then there's no hope for improving anything, because the kids who don't do well are going to pass anyway. This is how we end up with a bunch of graduates who can't actually do anything. I'm not saying you're wrong, but if you're right, then it's critical to fix that at the same time.

When I was in high school we got detention for not doing homework (Catholic school). I was a "smart" kid in honors classes, and at this time (late 90s early 2000s) Google was new as was SparkNotes and Wikipedia. I used them all. I plowed through homework just to get it done and avoid detention rather than actually caring about the material. I absolutely hated the strict and conservative environment of the school, so I refused to take notes in class (doodling instead) and almost never studied for tests. I'm probably in the top 1 percent of successful graduates of that school, and the most successful I'm aware of from the honors program in my graduating year. So yes absolutely, smart kids and rule-following academically hard working kids are not an overlapping group.

They're overlapping, but not the same group. Some smart kids are hard-working and eager to learn. Some are rule-following. Some are both. Some are neither. What I think you meant is that they are not dependent variables.

First, the smart kids who understand the material quickly will do just enough to make sure they understand it and then will stop wasting their time, but will still have feedback on the work that they did do.

I love that you didn't explain what the effect of this will be on the "not smart kids." Do you think they're going to hit the books and do a bunch of non-optional homework to learn the material? Have you met a single child?

The effect of this would be that the teacher would quickly intervene and tell the kid that they need to do more of the work, because they don't seem to have fully grasped the concepts. If the kids ignore this, then at the parent-teacher conference after the first six-weeks period, the teacher would encourage the parents to either make their kids do more work or put their kids in an after-school program that would do so.

And if that doesn't work, you can also make the participation points be contingent on whether they are grasping the concepts, where if it is clear that they're not getting it and aren't doing enough work to learn it, you tell them that they won't get participation points unless they do more of the problems.

You never could. Parents do their kids' homework all the time, or siblings, or friends. Ideally, teachers should give a large pile of optional homework. State right up front that although they will grade it, it will not count towards your final grade, and the grade on each homework paper will be given as a percentage of the problems attempted, not of the total set of problems. So if you do five problems and get them all right, you get 100, and if you do 50 problems and get most of them right, you get 90. At that point, the purpose of homework is primarily to help the students learn, rather than being primarily a way to evaluate the students. Give some participation points for doing some of the homework, but not based on correctness.

This has three benefits. First, the smart kids who understand the material quickly will do just enough to make sure they understand it and then will stop wasting their time, but will still have feedback on the work that they did do. Second, the teachers won't have to grade as much work from students who don't really need that much extra work. Third, no at-home cheating, whether by technology or by other people will distort their grades.

Obviously this doesn't work for everything — essays, for example — but for general homework, it's a big win.

Brief daily quizzes on the previous day's material will force them to.

You can certainly do that along with what I suggested, though I'm not sure how much difference it will make in the grand scheme of things.

Also, It's not like students have the excuse of, "I couldn't study, I didn't have anyone to explain X to me" anymore. The very AI that they might otherwise use to cheat on their homework can also explain to them the things they missed in last year's algebra class that are blocking them from learning this year's calculus, or whatnot. Congrats - you now have an infinitely patient personal tutor who will spend hours dumbing things down for you until you get it. Now you have no excuse - learn the material. It becomes all about actually putting the time in.

Agreed.

OK, off topic, but how do you display videos to somebody inside an MRI scanner? The magnetic / EMF forces those machines generate are pretty titanic, and any piece of metal gets sucked into the center of it.

Assuming it is installed inside somehow, you can avoid the projectile risk by not using any ferrous metal in its construction. Non-ferrous metals (e.g. dental fillings) aren't a problem in an MRI, though you may feel the electrical eddy currents induced by the magnetic fields. For something like an LCD panel, you'd probably want to shield the ever-living crap out of it to minimize problems, and I'm not even certain that it is feasible for that reason, but that's different from the LCD panel physically flying off the mount.

as evil is almost always necessary when the stated goal of your business is to maximize shareholder value at all costs

Don't interpret this as me having an opinion on this specific article (I don't), but that's a gross misrepresentation of what the law requires. As someone running a business, you *do* have a fiduciary duty to the stockholders, but that's not the same thing as requiring you to maximize shareholder value at all costs. Doing what is best for the company and the shareholders does not strictly mean more dollars.

For example, if a company had a choice whether to make a drone that would make a lot of money by selling to militaries, but would be used to annihilate the shareholders, no rational person would claim that the fiduciary duty requires them to build the drone.

More broadly, companies have a responsibility to behave ethically, for two reasons:

  • Perceptions of unethical behavior can impact a company's long-term profitability by discouraging customers/users.
  • Unethical behavior is often illegal, and when it isn't illegal, it often becomes illegal as soon as a company demonstrates that it is possible.

In other words, behaving unethically is how companies find themselves massively regulated in ways that negatively impact long-term profits. Every antitrust suit is an example of this, as the only reason those laws exist is because some company previously behaved unethically.

The older people get, the more set in their ways they become, and the less they like change. So basically, people become more conservative as they age, and less tolerant of things they don't understand. They also accumulate more wealth and favor keeping more of it (fiscal conservatism). And so on. This is generally a well-understood phenomenon.

When companies throw around terms like "cities and towns" for drone logistics, they are usually talking about sprawling suburban developments with neat, wide-open lawns, not dense urban cores.

Well, yeah, but those are still cities. Almost twice as many people live in parts of cities that are not "dense urban cores".

And the dense areas involve apartment complexes with hundreds or thousands of units and interior halls, so they're not delivering one package to the building; they're delivering a hundred. It wouldn't make sense to send drones for that.

But if you can handle the suburban sprawl with drones, that's a huge logistics win, because that's where all the time is spent — not by somebody going to an urban-core building and dropping a hundred packages in the mail room, but by somebody going to a hundred individual houses and dropping off a hundred packages one at a time.

I don't think that's correct? Possibly I'm misreading this, but it looks like the study involved giving two things, both the Keytruda, and a separate personalized vaccine.

You're not misreading it. It is individualized. Different cancers express different antigens, and the mRNA vaccine needs to construct something that expresses those same antigens to train the immune system to attack them.

The nice thing about mRNA, is that it is potentially relatively cheap to synthesize mRNA strands and replicate them. It won't be hundreds of dollars, but it won't be millions, either. Right now, I think it's hundreds of thousands per patient, but that will go down over time as they streamline the process of taking a sample of the tumor and determining an mRNA gene sequence that matches said cancer. And economies of scale on the equipment will also probably help.

It may also be the case that it becomes less individualized over time. At some point, we might reach the point where they have a bunch of pre-sequenced antigens that are all ready to go, and someone just keys in a list of antigens, and a piece of software spits out the mRNA sequence. At that point, it is still individualized, but with a much, much more streamlined process for generating it.

Note that I don't work in this field, so take all of this as the opinion of an educated layperson observer. :-)
