  1. You know, I've gone to Best Buy and gotten good help out of the salespeople. It's frightening. I have heart issues, and I don't need a shock like that.

  2. At the store, if it's in stock I can buy it today. If I ordered it online, it would take a day or two. Sometimes that's significant.

    That would require physically going into the building and waiting in line and talking to a real human - sometimes twice, as there are places that have had too many drive-offs and require payment in advance, then if you don't use all the money you need change. For what a gas discount would be on gas, I don't consider it worth it.

    There's reasons why I don't often use Paypal to receive money and never leave money in my account. It would probably be easier to use it more and leave some there, just as it would probably be easier to give Paypal my banking information, but I don't trust them.

    In what way do the doctors have too much power? They've got more knowledge and expertise than the rest of us, so they typically offer what treatments they think good, and the patient decides how to proceed among available options. You seem to think the options too limited, and seem to blame the doctors for not keeping obsolescent devices around.

    In a few of Heinlein's juveniles, people have phones on them at pretty much all times. This wasn't a technical prediction. It was a prediction of what people would want, with an assumption that we'd figure out how to do it.

    Any society with Earth-produced nonhuman intelligent, be it biological or silicon, will be an advanced civilization. It's reasonable to think that little things would be around.

    There's a movie "Cast a Deadly Spell" with "Phil" Lovecraft as a private eye in a world where magic was developed in WWII and brought back. There's a few subtle scenes of what happens. In one, a man cups his hand around a cigarette and it lights In another, an out-of-focus railway porter walks along in the background with a train of suitcases following the one he's holding.

    True, in the future we may not have anything recognizable as a smart phone, or comlink, or whatever. However, we aren't going backwards. Pay phones existed because people could not carry phones or the equivalent with them, and they're inferior to personal portable phones.

    I'm not paying interest on my loan, so it's in my best financial interests to not pay any of it early. I could have bought this cash.

    As for reasons, I've been supplying them: differences in the way Nazi Germany did things compared either to contemporary socialism or the Soviet Union. So far, nobody's disagreed with them. I'm not inclined to rewrite and rewrite them.

    The reasons you cite: (1) That meaning of "right wing" is almost completely useless today. It's now used for conservative and corporatist movements, which Fascism definitely is. (2) Fascist movements are nationalistic, mystical as opposed to materialistic, and frequently don't have a coherent philosophy. Socialism is internationalist, materialistic, and has coherent philosophies. In addition, while Mussolini and Hitler both dabbed in socialism, you haven't shown that the movements grew out of that. In Spain, Franco and the Nationalists were not and never were socialist. The same is true of fascist movements in other countries. (3) Traditional economic socialism has tried, and it has failed spectacularly, so what are now Socialists are concerned with the general welfare of the masses, which was not a concern (other than out of necessity) with Fascist governments. The people currently calling themselves Socialists are concerned with providing opportunity to all and social safety nets and the like, and have no quarrel with capitalism per se. They don't in general want to control private industry, but provide general restrictions. Fascists in general don't care about regulating industries, and typically keep big corporations happy.

    Are you actually going to tell me that what Hitler said has any relation, other than tactical, to the truth? IIRC, the Strassers led the socialist wing of the National Socialist party. One was expelled from the Party in 1930, and the other killed in the Night of the Long Knives. That was the end of socialism in the National Socialist party. In keeping with his principles on propaganda as expressed in Mein Kampf, Hitler kept up the public pretense that the Nazis were in some way Socialist.

    According to the original use, as you say, approximately everyone today is a leftist, including Republicans, the alt-right, and libertarians. The frames of reference changed to keep the distinction useful.

    Mussolini was not a socialist. Fascist Italy was definitely capitalist. I interpret his change from Socialist to Fascist as him being an opportunistic revolutionary.

    Stalin's "Socialism in one country" was a strategic move. Communism called for the Revolution to spread world-wide, and the Soviets were generally pushing that all along, including when Stalin was running things. It was a matter of putting building up the Soviet Union at a higher priority than spreading the Revolution elsewhere, not giving up on the plans to take over the world. "Socialism in one country" as a replacement for world revolution would have been a major ideology change.

    Interesting. However, unlike Go or checkers, chess doesn't scale up per se. There have been chess variants that used bigger boards, but they had new pieces.

    Given a rule for scaling up chess, apparently (according to the stack exchange question you cited), it's PSPACE-hard, which isn't quite the same as EXPTIME-hard (I'm not offhand very familiar with the complexity hierarchy above NP, but you should be able to use exponential rather than polynomial space given exponential time.)

    Look, everybody can take their shot at influencing public opinion, or the opinions of government officials. Think tanks do this by coming up with arguments. This is fine. Bribery is when an official gets something he or she values in exchange for influence or doing a particular thing, not when an official gets convinced that something is the right thing to do, or that the official's constituents want it.

  25. On the frightening premise that you may be serious:

    Of COURSE they're looking for errors. That's what mathematicians do. If they see a complicated proof, they look for possible errors, because otherwise it's easy to miss them. It has nothing to do with refusing to believe.

    If you can dig up a copy of Euclid, look at the very first proof, Proposition 1 of Book 1. If you just look at it, it looks convincing. If you are looking for errors, you are likely to find the error. If you just accept the proof as valid because it looks valid, you're wrong. Look for weak spots. Try counterexamples.

    Errors aren't necessarily fatal to the overall idea of a proof. If one derivation or assumption in a proof is invalid, it might well be possible to find an alternative to the erroneous part. This happens, and when the errors have been fixed (if fixable) the proof is valid.
