    Your argument is like saying no one needs a bigger outboard engine than the Seven Marine 557 HP, therefore there is no need for bigger ship engines.

    At the way businesses operate right now, current desktop computers are good enough. Same for enterprise servers. But there are plenty of tasks demanding more CPU power than we have right now. The only reason we do business that way is because we do not have good enough CPUs.

    Show me a computer that can take dictation the way a human secretary does. A machine that will not listen to the words "new display" and interpret them as "nudist play", that will not confuse a robot with a row boat. Show me a machine that can infer things from the context.

    We are still far in hardware capability from machines that can do simple things humans are capable of. There's plenty of room to grow. Don't let the fact that current machines are good enough for the tasks they do confuse you, there's need for more than text editing and spreadsheets.

    How we manage a transition from a jobs based economy, to a post-scarcity society will be very interesting.

    We are already doing that, with government-paid benefits. Every industrial country provides a lot of social services to the citizens. The transition is a bit too advanced at this point, since most governments are struggling with debt right now.

    The big problem will be how to automate government. I don't see public servants relinquishing their privileges any time soon, but an automated society implies necessarily in an automated government. If the jobs public servants do were more automated, like industrial jobs have become, the governments would be able to provide social services at much lower cost.

    What do you mean "robot"?

    Just FYI, there was a time early in the industrial revolution when steam engines didn't have mechanical valve actuators. There was a person with the task of opening and closing the intake and exhaust valves at the right times. In the sense that a job was eliminated by a machine, the camshaft in your car's engine could be called a robot.

    Assuming it IS a constitutional right, then a VERY strict check should be done to keep those guns away from deranged people. A guy who goes shooting people at random is not a member of "a well regulated militia".

    Anyhow, "the right to keep and bear arms" does not specify which arms. Under the current interpretations, there are lots of weapons that are not allowed for civilian use. A common citizen certainly cannot have a nuclear weapon, it's just a matter of where to draw the line.

    some people may not be accessing the market directly, but rather be trading by proxy

    Evidently, you have never bought or sold anything on the market.

    Everyone does business through proxies, they are called "brokers". You go through a lot of paperwork and pay a stiff fee to become a broker. There are a lot of regulations in place to make sure brokers comply to a set of ethical guidelines.

    If everyone had the same level of access to the market as brokers have today, we would have two nasty side effects.

    First of all, every transaction would be encumbered with a very high fee, which would mean only the very biggest investors could possibly get any profit from trading.

    Second, that would still leave the market operator itself in a privileged position, open to all sorts of corruption.

    A round could spend a couple of seconds executing the trades, then publish the results, add another couple of seconds for communication, and traders will still have six seconds for calculations before the deadline for the next trading round.

    Do you know how your system would work? The big traders would hold their trades until the last microsecond of the time block. This would happen no matter which deadline you use.

    Keep the quotes secret, you say? Well, I have some bad news for you. The big investment banks have information about the trades that go through them. They know the way the wind is blowing. You don't know that.

    The longer the latency is, the worse it is for the small trader. Information ALWAYS helps.

    High frequency trading helps the big guys without harming the small ones. I ought to know, I'm a private investor. I watch the prices and see big trades going through. There are times when my own trades are "big", When I buy $50000 of a small share the price may go up $0.07 as a result. I can "manipulate" the market just like the big guys do.

    It's just a matter of economy of scale. If I had more capital, I could invest more, but for the capital I have it doesn't pay to squeeze 0.001% more. My broker has a wide range of tools, I pay for those that fit my portfolio, it's as simple as that.

    Let the people who work the market and understand it create the rules, don't try messing with what you don't understand. Amateurs are likely to fuck up things.

  24. NOT a moment of insight! on Supersymmetry Theory Dealt a Blow · · Score: 5, Interesting

    Einstein's revolution was sparked by a moment of insight.

    Wrong, it was the result of long hard work by several people.

    It all started when Maxwell's equations gave results that did not agree with newtonian physics. In an attempt to get at the root of things, Michelson and Morley created an experimental setup to measure the speed of light in different directions in a very precise way. To everyone's astonishment, these experiments indicated that the speed of light is a universal constant, which does not depend on either the movement of the light emitter nor the movement of the detector.

    Which was exactly what Maxwell's equations had predicted to begin with! If there was a true intellectual giant here, it was Maxwell.

    Several scientists started creating equations that made the results of the Michelson-Morley experiment compatible with classical mechanics. Einstein was just the most successful one, because his equations were more elegant and simpler than those of the others.

    However, this does not mean Einstein was absolutely right, his theory was only the best one for that particular period. Today we know things he didn't know, just as Newton didn't know that the speed of light is constant.

    For instance, there IS a fixed frame for the whole universe, the one in which the cosmic background is symmetrical. This background was discovered only in 1965.

    There's also the horizon problem, which was discovered only in the 1970s. If we look at the sky in opposite directions, we see the same characteristics. We are looking at different regions of the universe that never had contact with each other since the creation of the universe. They are so far apart that even light couldn't have reached one from the other during the universe's lifetime. To solve this problem in a way that's compatible with einsteinian relativity, cosmologists came up with cosmic inflation, a rather ugly and contrived kludge.

    Besides, relativity does not give results that are compatible with quantum physics, this has been demonstrated experimentally.

    It's rather unfortunate that Einstein's theory is so elegant and precise, because it's certainly wrong when your size scales too much up or down.
