    Yep, if the nodes at the end are compromised, no amount of quantum kerfluffery will prevent you from being screwed. The specific application described in the paper referenced in the summary is secure communication between industrial controllers in critical infrastructure. One would hope this was an area where infrastructure builders would be better at security than "hey, let's make all our nuclear power plant controllers visible on the general internet, with default passwords, running an outdated version of the software riddled with exploitable holes" --- ideally, such devices would already be on a very restricted network, with minimal and tightly controlled links to the outside world, and abundant physical security at the endpoints. Of course, in the real world, a lot of critical industrial control computers actually are *incredibly stupidly exposed to the general internet with trivial or no security precautions* --- obviously, this is most important to fix first. But, once you do have a not completely stupidly vulnerable system , it might be useful to also fend off more advanced attackers who might actually splice into fiber links (even though the fact that today, with all the exposed vulnerabilities, factories aren't already blowing up left and right, indicates that even poor security is good enough against the general lack of attackers).

    Unfortunately, when you take away the unions, the lazy, self-serving, money-grubbing, too-useless-for-a-real-job, petty authoritarian teachers are probably the ones who will *stay* (and suck up to whatever teach-to-the-test nonsense that management makes pay raises ride on, or just outright cheat like the "incentivized" teachers in Michelle Rhee's DC schools). The great teachers, who have plenty of skills to get a much higher paying job elsewhere, but teach because they live for making a positive impact on their students' lives, will burn out and leave when management succeeds in sabotaging their ability to teach (I've seen this happen to a few of my best teachers).

    There's certainly some of both; however, I'd say even the specific knowledge learned in college should be done to provide a broader basis for figuring other things out, rather than learning how to use Corporate Software Tool v.3.8.71 (that will be completely obsoleted by Corporate Software Tool v.4.1.18 by the time you graduate). And, speaking as a person who was at the top of smart highschool kids --- learned calculus by seventh grade, worked in physics labs as a summer job, valedictorian at the city's top academic magnet school, highest number of aced AP exams in the state --- I *did* get *even better* at the "learning how to learn" stuff with four extra years of practice at a good university, while taking many classes with no "directly applicable" knowledge for anything I'll do. Yes, as a high school whiz kid, I would have been perfectly competent to leap right into doing mid-level technical work --- but, at least in my own experience, I'm a heck of a lot smarter (thanks to continuing educational work) now than I was then.

    I'm talking about the value proposition to the consumer for a particular good or service. Price AND quality.

    Yeah, I know what you're talking about. Unfortunately, there's little evidence that "marketplace" approaches are actually good at doing this. Instead, they tend towards consolidation, monopolization, advertising/branding over actual quality. You do know that the Walton heirs are some of the biggest investors behind the push for privatizing education, along with the Gates? A megacorporate monopolized approach is exactly what they're going for, and exactly what markets tend towards.

    Remember that at one point, McDonalds actually sold real food

    yet now they're bigger and doing better than ever selling McDonald's "food" (as is Wal*Mart selling their crap) --- I don't want to live in, or have my children grow up in, a country where the majority of citizens get a McDonalds/Wal*Mart education, and unbreakable addiction to corporate propaganda, even if I could afford to send my own kids to a higher grade place.

    As opposed to our current public education system with crappy quality at high and steadily increasing prices?

    There's more than one solution to the problems with the current educational system (which are exacerbated by increasing poverty and wealth gaps, created by the Wal*Marts of the world, along with "run education like a business" management-heavy test-and-metrics models).

    In every other market things get better and/or cheaper, or at the very worst, keep a constant value.

    Actually, in just about every other market in this country, things get increasingly unequal (larger divide between the "haves" and "have nots,") with the vast majority being subjected to a race-to-the-bottom for crappy quality at low prices. As McDonalds is to quality nutritious food and Wal*Mart is to high-quality, durable goods, so too will privatized corporate education be for the masses. We'll get empty-calories education, all corn syrup and hydrogenated soybean oil, with the lasting durability of a made-in-China plastic widget --- and maybe somehow the quantity will make up for the quality? Well, at least it will make the owners very, very rich.

    The problem with a simple "tiered" model is that it assumes all kids are either uniformly brilliant, average, or dumb. While there are a few who simply fall into such categories, many more will be great at some things and poor at others. Should the kid who's a math whiz, but reads below grade level (or vice versa), be shuffled into the dumb kids school, or the medium (and in either case, suffer incredibly boring work in their area of skill)? I agree on separating subject-matter specific classes by ability level, but when you track whole humans into dumb/normal/smart (with corresponding buildings for each), you're going to badly screw the majority of people over (who might turn out to be brilliant at some class of endeavors, if they weren't locked in a soul-crushing prison to be taught that they are a dumb kid, whose only career prospects are janitorial work or fry chef).

    I enjoyed the benefits of going to a public magnet school segregated for the smart kids --- but I very nearly ended up in the regular zoned school (because there weren't nearly enough magnet school spots, handed out by lottery, for all the qualified students). The short time I spent at the regular zoned school (geared towards "normal" students; even the "honors track" classes were dull) was mostly miserable --- and I wouldn't wish that experience on anyone who either "lost the lottery" for magnet-school placement, or wasn't up-to-snuff in one particular subject area. Ideally, you need a system where you can offer a variety of paces in different subject areas in one place, rather than lump everyone into "overall smartness" categories.

    (3) Stop teaching to the test. I understand (at least where I live anyway) that school budgets are tied to SOL test scores, but it screws things up, and makes it worse, not better.
    (4) Dump the teacher's union. Give teachers the authority to make the changes needed in education.

    How is "dump the teacher's union" supposed to fit in with the rest of this? Despite failings, the teachers' unions are the *only* thing giving teachers any sway over the educational system. Without that, it'd be entirely up to management types --- who've been trained from birth to absolutely love making everything into shallow numerical metrics (teach to the test!) to prove how important management is. Yes, I had to suffer through some bad teachers kept around by the unions --- but all the *very best* teachers I had would have been first to go if management had their way, because sticking up for smart students puts you on the wrong side of management priorities.
