I'll be honest, I'm kind of enjoying 'Aviation Week' here on HN. This is the kind of stuff that got me interested in math and science to begin with. Too bad my vision is so awful.
Nevertheless, here we are. And here, most importantly, at least from my perspective, I am. And - or perhaps, "and so" - I enjoyed this one.
The YF-12 was to kill however.
Just as one can use a butcher knife for its intended purpose or use it to kill, it's possible to design military equipment to "kill people and break things" without necessarily meaning to wage aggressive warfare.
It's true that the military tools are often misused, but that wouldn't change in the real world by simply not having them; pacifist countries are sheep in a field full of wolves.
Just look at Ukraine, and then compare to nations that e.g. gave up nuclear weapons and then suffered "regime change". The list includes Libya, parts of Ukraine, and effectively Iraq (who were very close to a nuke circa 1991). There's a reason Iran and North Korea want the bomb, and that reason is because the deterrent value is real, not imagined.
Rather it's the same as an underlying principle behind the Second Amendment push (no one cares for my defense more than I care for my defense), scaled up to the geopolitical level.
So just as I think it's possible to appreciate the craftsmanship and design that goes into a well-made katana even if you don't intend to run the sword through someone's guts, I think it's possible to appreciate at a technical level some of the technology used in military gear without feeling like it means you support war. ;)
http://en.wikipedia.org/wiki/Lockheed_YF-12First thing I'll say: I'm not sure I've reached a conclusion regarding that statement or not.
But I've been leaning rather more strongly to the idea that things can be classified as beneficial vs. otherwise. Though sometimes counterintuitively.
One of the more interesting hypotheticals I've run across recently is the Paperclip Maximizer example: http://wiki.lesswrong.com/wiki/Paperclip_maximizer
The paperclip maximizer is the canonical thought experiment showing how an artificial general intelligence, even one designed competently and without malice, could ultimately destroy humanity. The thought experiment assumes an AI stable structure of goals or values, and shows that AIs with apparently innocuous values could pose an existential threat.
The idea: any simple-minded optimization behavior which doesn't take into consideration human values can, taken to the logical extreme, prove hazardous.
It was posted to HN a few years ago, though it didn't trigger much discussion at the time:
It does open some questions about how "innovative" one might want to be when developing a weapon, even for defensive uses.
It's sort of unfortunate that nuclear physics made the gains it did, when it did, as a big part of the reason the U.S. ended up making the big push for the bomb, at a time when they needed all the resources they could get put into things like logistics for shipping materiel, was because of the fear that Germany might get it first. I.e., "if someone will get the bomb, we'd better do it better they do".
I suppose the Cold War would have ensured proliferation one way or another, but WWII certainly did not help the cause of non-proliferation.
But either way, war or defense (whatever you call it) can never be a simple-minded optimized anything. It is almost the very highest level of human holistic competition. So I'm not worried about the technology (as long as we don't make it self-aware, of course), I'm worried about the people.
It's not enough to merely keep humans in the picture, but to keep healthy, undamaged humans in the picture.
Let's say, perhaps, that after a particularly costly war, the only humans left are a mixture of mentally unstable, angry, ambitious, victory-driven amputees, with intense biases imbued upon them by surviving particularly horrific and violent combat. These people, in a warped attempt to say "never again", optimize an artificially intelligent, fully automated child-rearing skinner box [1] to mold children into their own image, as the natural and perfect outcome which produces a society averse to violent warfare. The result is that every child that emerges from the skinner box is an angry, warped sociopath, missing limbs, who rationalizes even trivial behavior with an arbitrary moral high ground of extreme polar ideology.
But wait... aren't humans... technically classifiable as self-assembling intelligent constructs, spewed forth from the bald nothingness of space and time by mere coincidence? What if WE are the beast we fear?
Oh... oh god.
That's helpful but not sufficient.
• It doesn't address the criticality of appropriate feedback controls and limits. People and algorithms both make bad decisions.
• A given group of humans might not act in the best interests of all humans, or even a specified larger group, or even themselves.
Re: how innovative we want to be even with defensive weapons. Body armor is generally far less dangerous than an RPG or assault rifle. But defensive technologies such as antibiotics can, if misused, lead to larger downstream threats (through antibiotic resistance). The areas of unintended consequences, moral and morale hazard, and the like, make for fascinating study.
Re: the bomb. Yes, the Germans and Japanese were both conducting nuclear research (though I believe the Japanese project was limited and/or curtailed). Another interesting speculation I've seen is of what might have happened had the US not used the atomic bomb on Hiroshima and Nagasaki: it's possible that the true horrors of the weapon wouldn't have been realized and that the next military action (the Korean War) might have gone nuclear.
The places where I've been spending time looking at things are a bit more nuanced though: sustainability in light of finite resources and/or maximum flows: is saving lives really an unalloyed good? What of technology in general which might increase technological risks (simply of failure). Was the Green Revolution a good thing? Humans have been something of a paperclip maximizer, except that our paperclips are humans. In the long run even that may not work out for us. Systems need negative feedback loops.
Imo, the whole electronics (tv, computer, chip) industry advanced as much as it did due to the War Machinery.
My son is almost 2 and you can bet that I'll tell him what he needs to do to achieve this. [1]
[1] - To be a USAF pilot, your best bet is to bust your ass in high school and be both a student and an athlete and secure one of the coveted congressional endorsements to the U.S. Air Force Academy, where you must bust your ass and hope for a flight slot. Similar route for the Navy and USMC: U.S. Naval Academy.
The process to become a U.S. Army helicopter or fixed-wing pilot is a lot easier. Pursue a slot as an Aviation warrant officer. Successfully complete basic training, WOCS, and flight school. You don't need a college degree but it helps. The key is age: the doors close at around 32, so you have to start early.
(I also spent an evening at the bar w/ a class of his students. I was expecting super gung-ho jock types, but they were actually very laid back and a little bit dorky. Interesting experience for a boy raised by hippies in the Oregon woods.)
