    If there were a real-names policy (an actual, checked, real-names policy, not bullshit like what Google tried to pull), one would surely see less trolling.

    One would also see less insightful posts, since any kind of insight typically steps on the toes of some entrenched interest. And even on Slashdot posts expressing unpopular opinions typically end up downmodded because, after all, if it provokes you, it's a troll.

    A forum with real-names policy is basically worthless, which is precisely why the Powers that Be try to push them. Stripping people of the shield of anonymity makes dissenting opinions easier to silence through chilling effects. And of course this is marketed for our own good, after all we all know that having someone get away with posting something offensive on the Internet is the worst thing ever.

    But now let's totally eliminate the barrier between graphics, sound and all other processors. Instead of limited communications channels and local memory, have distributed shared memory (DSM) and totally free communication between everything.

    This sounds a lot like NUMA. Which, I might add, absolutely requires differentiating between local and non-local memory, since the latter is much slower.

    Thus, memory can open a connection to the GPU,

    Like GPUs have done since the time of AGP? Or did you mean memory will simply send some random data for no particular reason?

    the GPU can talk to the disk,

    For what purpose? Do you plan to write a file system driver that runs on the GPU? To accomplish... what, exactly speaking?

    Ethernet cards can write direct to buffers rather than going via software (RDMA and OpenSockets concepts, just generalized).

    Haven't they done this a long time now? In fact, don't all devices that do significant IO use direct memory access?

    What room, in such a design, for a CPU? Everything can be outsourced.

    And the part that keeps track of the overall program execution state and issues these outsources tasks to other components is, for all intents and purposes, a CPU.

    Have the router elements take care of heat and congestion issues, rather than compilers.

    ...What the heck are you talking about?

    And this is marketspeak? Marketspeak for what? Name me a market that wants to eliminate complexity and abandon planned obsolescence in favour of a schizophrenic cross between a parallel Turing machine, a vector computer and a Beowulf cluster.

    None does. It's the "schizophrenic" part that's the killer. Which is why, if you need to sell garbage anyway, you litter your product description with enough trendy buzzwords to convince technologically illiterate that it's cutting edge high tech. Which, if you are trying to polish a particularly smelly turd for a sale, can end up using almost all of them. And that can have great synergy with illusion-challenged human resources seeking a solution for cynicism management.

    That right there is economist talk, and do not hold up to a reality check what so ever.

    You have a very odd view of reality.

    Idle production equipment is not wasted.

    By definition that which is not used is wasted.

    Idle workers are not wasted (unless they happens to still get paid).

    Idle workers still need to eat, so either the factory pays them or the taxpayer will. But unfortunately, with all economic activity crippled by lack of energy, just like the factory was, there are no taxpayers any more, so there seems to be a small problem.

    Sure, there is a "loss" of potential profits if the market is screaming for the widgets the factory is providing.

    That, and people aren't getting the widgets. That's too bad if it's an iPhone factory, and worsel if it makes heart medicine.

    But unless some book worm economist set up the whole gig, every damn widget produced, be at 0.01% production capacity or 100% capacity, is a profit earner once sold.

    This might surprise you, but both buildings and machinery require maintenance. Furthermore, neither raw materials nor products simply teleport around, and the overhead of moving them is the greater the less you have. And finally, as I already noted, a lot of production processes can't simply be arbitrarily slowed - apart from chemical factories, how about things like casting molten stuff?

    The 'Corrie Break' is a very well-known example, occuring predictably during the mid-episode break of Coronation Street in the UK - it's caused by millions of people simutainously going to put the kettle on.

    You want real value for your real things.

    The problem, of course, is that they're your chickens and land only because people agree so. Property rights are no less imaginary than currency.

    The truth of the matter is that "value" is an entirely made-up concept. A chicken has no property of being valuable; all value you ascribe to it is entirely in your own imagination. Which is of course what allows people to value things differently, thus making trade possible. So it's only appropriate that we use a made-up concept of currency as an abstract representation for the made-up concept of value - or economic value, to precise.

    In other words, there is not - and cannot even in theory be - non-funny money. Value being subjective is the very heart of the concept of economy. And that means any imaginable way of measuring it is ultimately just make-believe.

    Well, no, because I have no convenient way of checking either the purity nor mass of any gold I might get, and a metal-backed currency can stop being so at any time. On top of that, gold is soft enough for wear being a problem, but still too hard to cut pieces off as needed, so we'd be stuck with precut gold pieces (coins) which can't be actually trusted to carry their nominal value due to wear and theft.

    On a purely technical level, without getting into any economics or ideology, gold makes for a horrible currency.

    No, it isn't. I need power for food storage, food preparation, Internet access and light. I also consume water, which takes power to prepare and pump. Trying to make any of these too expensive for me to afford - which is the reality behind talk of "incentives" - means it's time for torches & pitchforks.

    Turn a factory on full power when the wind is blowing and slow it down when the wind isn't.

    This means the factory is running at less than full speed on average, making it less profitable and thus more prone to be shut down. That's bad news for the employees and owners both. And that's assuming the factory can simply "slow down". Try reducing power to a chemical plant and it'll enter an emergency shutdown mode, hopefully only losing the raw materials under processing at the time (as opposed to, say, having them solidify in pipes or reactor vessels, or even outright exploding) but coincidentally creating work for hazardous waste disposal companies.

    OpenCL is highly specific in application. Likewise, RDMA and Ethernet Offloading are highly specific for networking, SCSI is highly specific for disks, and so on.

    Well, since the CPU already specializes in general-purpose serial computation, other nodes in a heterogenous environment must logically specialize for either generic parallel computation or specific applications, otherwise you have just plain old SMP.

    But it's all utterly absurd. As soon as you stop thinking in terms of hierarchies and start thinking in terms of heterogeneous networks of specialized nodes, you soon realize that each node probably wants a highly specialized environment tailored to what it does best, but that for the rest, it's just message passing. You don't need masters, you don't need slaves. You need bus switches with a bit more oomph (they'd need to be bidirectional, support windowing and handle multipath routing where shortest route may be congested).

    That describes neither how this heterogenous network of equal nodes would function (how do you dispatch tasks to nodes without the dispatching node becoming de facto master) nor what advantage it would have over current model (heterogenous network of nodes with some specializing in overall control). In fact it sounds a lot like buzzword bingo.

    Above all, you need message passing that is wholly target-independent since you've no friggin' clue what the target will actually be in a heterogeneous environment.

    As you surely know, coal plants are huge polluters and pollution causes health issues, which in turn add up to early deaths, even if we ignore damage done to environment.

    But then again, opposing nuclear power is not really about protecting humans or nature, now is it? It has long since turned into politics, where opposition is based more on identity than rational calculation of risks and rewards of various options. And who knows, perhaps being hit by the double-whammy of full-power climate change and energy crisis simultaneously will finally teach humanity to not treat important decisions as tribal identifiers. It's something we must learn before we venture beyond this planet, since the cost of irrational stupidity will continue getting higher. But I fear the lesson will be exremely painful, even by the scale of these things.

    And: fix your damn mining safety issues instead of blaming it to 'coal', mining of uranium is only marginally more safe.

    Thousandfold decrease in mining causes a thousandfold decrease in mining-related deaths, even before factoring in such details as coal being highly flammable and uranium being not. Also, unlike coal, uranium can be extracted from seawater, so with it we could theoretically eliminate mining altogether.

Bankruptcy is inevitable unless the restaurants can lure some customers working at the manufacturers of said supplies and close the cycle of money. Too bad such customers get ever harder to find as industry gets automated.

    Services have a supportive role and can't carry the economy. A wealth of society is roughly how much stuff it produces per citizen. As industrial workforce shrinks, a smaller and smaller proportion of that enters economy through Joe Average and higher and higher proportion enters through Joe Shareholder. But no matter how gluttonous Joe S is, there's physical limits to how much he can eat, so the restaurant is screwed, regardless of how many other people might like it - they simply don't have the buying power to keep it afloat.

Since US - and increasingly other Western countries - seems hell-bent on making almost everyone poor for the sake of a few ultra-rich, it's quickly approaching the point where it must indeed switch to planned economy, since a capitalist one is inherently controlled by demand, yet people who can't afford what they need can't send signals to control production.
