    While they (mostly) don't admit it, the Israelis are known to have a few hundred nuclear weapons. No doubt they have hydrogen bombs. While they don't openly test, there was what was thought to be a nuclear test in the ocean off of South Africa a while back. Even if they don't test, Israel has no shortage of smart people, or computers capable of accurate numerical modeling.

    The Vela Incident on the Prince Edward Islands (the other ones) probably was a misfunction in a satellite that looked for nuclear tests, because a lot of people spent a lot of time looking for fallout or radioactivity and didn't find much. But if it was an actual test, it's more likely it was a South African device rather than one of Israel's. Israel appears to have had access to US weapon design information, so they can probably do a good job without needing tests -- and really, all they need is to appear to have nukes.

    Just because there is a continuum does not mean that we cannot figure out a reasonable point to draw the ethical line. Your premises are (1) that engineers are involved in building stuff and (2) that stuff can hurt people. Your premises are valid. The logic you use to make your argument is not. You might use the same style of argument to say that, when hitting babies, it is too hard to draw a line because some people are ok with it and some people are not and that there is a continuum of softly holding them to beating them to a pulp. Still, you could in fact be right that engineers are without responsibility for how their products are used, but this is not clear from the logic you employed.

    I don't actually think engineers are without responsibility for how their products are used. However, I do think that there are engineers who feel completely justified, and completely good, about building systems whose most obvious use is killing people. Furthermore, it's not obvious to me that I have any high moral ground for telling them that they're wrong. *I* might think they're wrong, but I'm just some dude, and it appears to me that their premises for working on such systems are logically consistent to them, and their conclusions are likewise good. As such, I don't think there is any absolute truth supporting me if I should question them.

    As for your babies analogy, as someone who has spent a lot of time shoeing horses, I do not think it's right to beat horses with baseball bats, but I certainly do think it's right to smack a horse on the flank with my hand when it's leaning on me again.

    Unless your job is designing large shapeless soft foam objects, you're always going to risk someone using your creation to hurt someone else, and at each point along the continuum from plastic bag designer to nuclear weapon designer, at least a few people are going to say they're not comfortable with doing that, and at least a few people are going to say they are.

    Oh please, weapons are built with the purpose of hurting, or forcing someone do something you want (under threat of hurting him). Cars and garbage bags have many other uses besides killing.

    Speaking as a person who is in favor of gun control legislation, I use guns as tools for protecting my workshop from having holes punched in it by woodpeckers. (Stupid woodpeckers. I build them birdhouses, but they'd rather cut holes in the siding.) In a similar way, peace through strength, or "if we don't have a weapons system, they'll roll in and take us over", has clearly been an effective tactic for North Korea. As such, I believe it's incorrect to say that weapons are built with the purpose of hurting people. They can be built with the purpose of preventing people from getting hurt by ensuring that nobody on either side dares use them.

    And, seeing as cars have killed roughly 1000 times more people than nuclear bombs in the last 100 years, I don't think it actually matters what the *purpose* of a tool is. What matters is how it is used.

    But in the broader context, what you're talking about is a continuum of engineer responsibility: engineers who design guns have no control over whether people use them to shoot people, engineers who design cars have no control over whether people use them to run over people, and engineers who design garbage bags have no control over whether people use them to asphyxiate other people.

I'm not sure how one would draw a line at any given point and make a decision that beyond that point, other people were Bad People for continuing to work on those designs.

    See above response to graft: there's a reason that after a billion years, the vast majority of mtDNA has migrated to the nucleus but the same few genes are retained in mitochondria across at least dozens of species of eukaryotes, from amoebas, through trees, to humans. If we are going to do genetic engineering on mitochondria, that isn't what we need to be doing to them. We need to be making mitochondria increasingly leakproof, increasingly efficient, and much more numerous. Then we should see some dramatic changes in lifespan, and I mean doubling or tripling standard human lifespan. (According to one current and reasonably well-supported theory, that is.)

    Man, once our genetic engineering is good enough, one of the first things we should do is migrate those mtDNA genes into the nucleus, already, and get them working under proper sexual reproduction/selection. Clean that shit up.

    Bad idea. Somewhere between 80 and 99.5% of the mitochondrial DNA has already migrated into the nucleus (comparing to bacteria that are somewhat similar to what we think mitochondria were, like Rickettsia sp.) because when an individual mitochondrion dies, it breaks apart and its DNA is floating around where it can easily be picked up.

    Since there are significant differences between retained mtDNA in different animal and plant species, but there are *always* (as far as I or apparently anyone else knows) the genes for cytochrome C oxidase, ATP synthase, and NADH reductase, and apparently that's been the case for a billion years, it's pretty likely there's a good reason for it.

    Currently, the assumption is that there IS a good reason for it, and that is: as a mitochondrion ages and gets damaged, it needs to change its metabolism compared to other mitochondria in the cell. There isn't any way for protein from the nucleus to be specifically built for and exported to one mitochondrion. (There are often 100,000 mitochondria in a single cell, and while there is something akin to a packet header on exported proteins, it basically says "put this in mitochondria" rather than "put this in mitochondrion #9634".) As such, mitochondria *need* to retain that DNA as a fundamental part of the metabolic regulation system.

    What we need to do, once we get better genetic engineering, is to talk our mitochondria into replicating more, so we have a higher density per cell, and fiddle around with the damage feedback system. Then we'll suddenly be on the life path that birds have, where they live several times as long as mammals who have a similar size and do so with very little signs of aging.

    Not only that, but since the mitochondrial DNA only codes for a small amount of the respiration chain -- cytochrome C oxidase, ATP synthase, and some of the core proteins of the NADH reductase complex, in most eukaryotic cells -- while the nuclear DNA codes for much of the rest of the proteins in the respiration chain, you need to have an excellent match between proteins that come from two different chunks of DNA. There's no guarantee that'll happen, and there's evidence that one of the reasons cloning has such a poor success rate and so many cloned animals die young of strange damage, is precisely because of poor matching between mitochondrial and nuclear dna products, leading to oxidative damage throughout the cell and early cell death because of leakage from the poorly-functioning respiration chain.

    There are scads of youtube videos of multi-axis machining, from impellers to V8 engine blocks, that are several years old. But, way before youtube, in the 1970's, Japanese nine-axis milling machines helped Soviet designers make submarine propellers vastly quieter, meaning subs like the Soviet Typhoon-class were roughly as quiet as American subs had been for a while. The military and export implications of multi-axis milling machine technology was mentioned in US Congress debates at the time: In 1983-1984 the Japanese firm Toshiba sold sophisticated, nine axis milling equipment to the Soviets along with the computer control systems, which were developed by Norwegian firm Kongsberg Vaapenfabrik. U.S Navy officials and Congressmen announced that this technology enabled the Soviet submarine builders to produce more accurate and quieter propellers.

    Promiscuity: an evolutionary history of sperm competition by Tim Birkhead, talks very little about humans but discusses (in great detail) how and why out-of-relationship and non-relationship sexual contact can benefit different reproductive strategies.

    The Moral Animal: Evolutionary Psychology and Everyday Life by Robert Wright, which talks about how often our behavior seems to contradict our professed beliefs but how very well it matches evolutionarily successful mating strategies, and

    The Stuff of Thought: Language as a Window into Human Nature by Steven Pinker, especially the second-to-last chapter which specifically addresses how ambiguity can be modelled in game theory to show huge advantages to people who use it skilfully.

    In short, what people say they want isn't always what they want, but they often don't know that. They're unconsciously using successful strategies they don't actually understand, because we seem to instinctively know what works and what doesn't. In this specific case, there are many animals with mating strategies similar to humans, where females who aren't a male's primary partner benefit heavily from providing sexual access to, and receiving resources (money, food...) from, the males in question.
