    Of course gods are imaginary, and you can't really say that the imagined central character inspired a piece of fiction. That would be crazy.

    God(s) may or may not be imaginary, but many works were inspired by imaginary characters, and any long-running series tends towards "character X meets situation Y and reacts".

    Thats an exercise on futility; the conditional probability of an event happening given that it happened is always 1.

    Isn't the whole point of quantum physics that the condition - "something has happened" - is in itself a fractional number? For example, a photon does not go through one slit or another, but both, and these histories interfere with each other to produce the interference pattern on the wall.

    Which, of course, is the answer to the qproblem about apparent causality violations in quantum mechanics: no, observing one of entangled particles does not send a FTL signal to the other paricle; any point in spacetime where you can compare observations of both is by necessity causally linked to both, and these pasts interfere with each other to promote those combinations where purely random chance caused a seeming linkage over those where it didn't.

    Not that you can ever prove an event happened even in classical physics. No matter your observations, you can never know if you have all the relevant facts; "Last Thursdayism" is undisprovable, even in principle.

    We know that the universe itself is a finite age, and it did not always exist....

    No, not really. Time is a property of the physical universe, so saying "universe did not always exist" is an ill-defined concept - it's referring to a point in time before time began. And since time is governed by General Relativity, which is incompatible with out current theories of quantum mechanics, saying anything certain about how it behaved in an early universe is extremely difficult.

    The only question remaining is how long it will take for tech workers to pull their heads out of their asses and realize that half of them will never afford retirement at the current pace of things.

    They realize it all right, they just all think they're better than average. Thus efforts are focused on increasing wage gaps so the superior half can soar unweighed by the sheeplike masses, and when that fails to improve your lot, it's clearly because you're still supporting too much dead weight rather than because you're just an average person. There's nothing worse than mediocrity, after all.

    Because it's impossible to limit it to just them. In a world where labour is already in oversupply, and employment a requirement to function as a part of society, letting someone consent to X to gain a competitive advantace de facto forcing others to consent to X as well.

    No, dozens aren't getting the information at the same time. They get the information when it enters their past light cone, which for some is later than for others.

    HFT is a very competitive space with hundreds of firms doing it and competing against each other. They all have access to that information at the same time.

    I don't really care what sneaky leagalese was in their TOS that justifies them legally.

    What makes you think anything does? They marketed a lifetime service; while it's obvious that no one and nothing can guarantee it's going to live longer than you, it seems that No-IP is still around, so why not take them to small-claims court and demand your money back?

    They explicitly sold this service as "lifetime", and I feel this was a completely underhanded move.

    And it is. So, even if the TOS actually does legalize this kind of thing, it's entirely possible that you might get yours back by pointing out this fraudulent advertising. Perhaps you could see if you can get a class-action lawsuit going - you can't be the only victim?

    Probably actually. It's way easier to manage that way. It also solves tons of problems.

    The problem is... that's also true of all always-on connections. The whole reason we got dynamic IPs in the first place is that a 300-line ISP only needed one IP per line, not one per customer. But an always-on broadband customer needs one IP per computer, and the only question is whether they're public or behind a NAT. IPv6 removes the need for NAT, but does not solve the "need" for a dynamic IP for a broadband customer since there never was one in the first place, except for greed. And, sadly, technology can't solve greed.

    Why a lack of anonymity is a nightmare to you? Is it because you don't live in a free country and the only way you can express your ideas without going to jail afterward is with anonymity?

    In no country can you express any actually significant idea without making enemies. Powers that be want nothing so much as status quo, since that means they stay on top, and any significant idea by definition threatens it. Anonymity is absolutely vital for any society, since it allows unpleasant truths to be expressed without fear of legal or extralegal punishment, whether it comes in the form of jail, vigilantes or unemployment.

    Furthermore, as Manning and Snowden showed, even nominally free countries tend to have boils of corruption which need to be exposed to be healed - and we can't rely on always having a hero ready when we need one, thus such exposition needs to be possible anonymously.

    And of course there's the "knowledge is power" -aspect, where the state being able to casually record everything its citizens do online (and increasingly offline) simply makes it too powerful to resist the temptation to abuse said power.

    If there was a reliable implant that could detect anti-government sentiment in a person's thoughts the North Korean government could easily decide to implant it in every child at birth.

    Would Kim be stupid enough to do so, though? Dictators don't stay in power with brute force; they don't have magical powers capable of subduing millions of ordinary people. They stay in power because people think it's safer to not do anything than to resist. Put a thought-reading implant in them, and they no longer have a choice: any dissident thought means they've been cornered and must fight or die.

    The more you tighten your fist, the more star systems slip through your fingers - because it makes participating in the lie, the masquerade of benevolence, costlier. And North Korea has nothing but the lie. A country that turns its army against its own people has already fallen, because you can't win a war against the same people who supply that army. It's just a question of how long the insane situation goes on before the inevitable collapse.

    Of course, this might make Kim desperate enough to instigate a war against some neighbour simply because he has no other hope of staying in power than a distraction. While that would of course result in North Korea being turned into rubble, I think its rulers have proven beyond reasonable doubt to not give a tiniest bit of a shit about that.

    The difficulty is that wave-function collapse is not local. This is inherent in the mathematical logic of quantum mechanics.

    Does wave-function collapse have any actual, physically detectable consequences? Because I can't help but note that we've been down this path before, where we force observations into our familiar mindset, which evolved to avoid getting eaten by bears, not learn particle physics.

    So why we could postulate spooky action at a distance, we could also explains observed correlations by saying that the first observation event changed the observer and culled (destructively interfered with) any future where the second quality is observed as not correlating with the first.

    In other words, wave function doesn't collapse, you're just making an incorrect assumption - specifically, that each observation event is independent of those that came before. Or, rather, your observations don't collapse the superposition of the observed, they put you into a superposition.
