    The trouble is that the effect is correlated with the 33-day rotation of the solar core. If varying rates of nuclear decay affected cancer rates -- which they could -- the problem with measuring it is the speed with which cancer progresses. Since we can't detect cancer the moment a cell goes rogue, any variability in oncogenesis rates over a 33-day period would be lost in the statistical noise.

    If you do figure out a way to detect oncogenesis that precisely, you'll be too busy curing cancer to worry much about solar neutrino flux.

    We don't have more than a rudimentary understanding of how the brain works, or even what consciousness is.

    People say this a lot, and I don't understand why. Our understanding of how the brain works is a good deal more than rudimentary. The advances we've made in understanding the brain on both the large and small scales in just the last five years are breathtaking. Our understanding is a long way from complete, but Kurzweil is correct at least to the extent that our understanding is significant and appears to be growing at an accelerating rate. It may not be accelerating as fast as he expects, but keeping up with new developments in neurology at even a cursory level is quite challenging. The main difficulty we face at present in implementing the structures we do understand in silicon is the lack of adequate parallelism in current computing hardware, not our understanding of the relevant neural structures.

    As for consciousness, unless you believe in some kind of pre-scientific vitalism, a reasonable working assumption is that it is an emergent property of brain-like structures. Unless and until we discover otherwise, there is no reason to wait for an understanding of consciousness to begin working on replicating the functionality of the brain. Quite likely, the attempt to replicate the brain will reveal more about consciousness than idle philosophical inquiries. Those so inclined might want to settle on a definition of consciousness before trying to figure out how it works.

    I would argue that there is an evolutionary advantage to the brain being structured, because this is consistent with structured encoding in DNA. The encoding in DNA will tend to be structured because this minimises the use of energy and other resources.

    That's certainly true, as far as it goes. But the structure of the brain is not explicitly coded in the DNA. One of the energy-conserving features of complex organisms is that their gross structure is an emergent phenomenon, much the same way that, for example, the infinite complexity of the Mandelbrot set emerges from a very simple iterative equation. Reverse-engineering the brain is thus a bit like taking a rendering of the Mandelbrot set and trying to deduce the original equation. Starting from DNA is like taking the equation and trying to predict the value of an arbitrary point on the complex plane. Both are intractable problems; the latter may be undecidable as well.

    Mind you, I think strong AI is possible. I just think that successfully reverse-engineering the human brain is one of the least likely ways for us to get there.

  8. A mild defense of Kurzweil on Ray Kurzweil Does Not Understand the Brain · · Score: 3, Insightful

    First off, Ray Kurzweil doesn't want to die. That's a preoccupation that a lot of people have (including one of his critics, Rudy Rucker, who has written whole books hoping to find immortality in the fourth dimension), and it leads them to some pretty fantastic conjectures from time to time. It's not necessarily a bad thing, as long as you keep the proverbial grain of salt handy. Modern chemistry and its not insignificant contributions to our vastly expanded lifespans arose from the alchemical search for immortality. Alchemy was bullshit, of course, but the incidental discoveries of alchemists on the way to their illusory elixir of life paved the way for the real science to follow and build upon after it had ejected the dross.

    And secondly, I don't think it's entirely implausible that we can eventually design hardware and software that will match and exceed the performance of the human brain. Our brains, after all, are the end product of evolution, and like pretty much every other part of our bodies, an accumulation of kludges that were just good enough to get passed to the next generation (or not bad enough not to get passed on). It's also implemented using hardware so unreliable that it wouldn't function at all if it wasn't constantly repairing itself, and even then, no matter how well you treat it, it irreparably craps out after about 75 years. And it still doesn't work all that well -- ever seen the long chain of train wrecks that is the history of human civilization? We might be able to engineer something that works a lot better. Granted, it's not going to be by deriving simulated human brains from a copy of the human genome. More likely, it will be very much unlike the way biological brains work.

    The fundamental problem, which I think smart and optimistic guys like Ray Kurzweil are particularly prone to forgetting, is that it may not be possible for a mind to understand a mind of equal complexity, i.e., humans may lack the necessary intelligence to duplicate their own intelligence. That will force us back on genetic algorithms to evolve AI, leading to an end product that will likely be just as badly undesigned as natural brains. Worse, it will do little to advance our understanding of how minds work: if we can't reverse-engineer our own brains, we probably won't be able to reverse-engineer even more sophisticated artificial minds, nor will they be able to reverse-engineer themselves. (We can hope that they could reverse-engineer us, and then explain it to us in terms we can understand, if such terms exist, but that takes us so far out on a conjectural limb that I can see Ray Kurzweil from here.)

    Anyway, there's room for bold conjectures. That doesn't mean that when Kurzweil completely fails to understand the way molecular biology works that we shouldn't call bullshit on it, but we shouldn't be entirely hostile to futurist speculation. By nature, most of it will be bullshit, but a lot of progress in unexpected areas has been made in the pursuit of mirages (alchemy leading to chemistry, astrology leading to astronomy), and explaining (or discovering) why a conjecture is bullshit is a beneficial exercise in and of itself.

    You just described a mixed economy having a central bank that controls the money supply, not capitalism. The United States has never had capitalism, only a mixed economy. This leads always to monopolies and corporate manipulation with government. Please explain how a corporation could establish itself as a monopoly without the legal use of force, i.e. government.

    In some cases, it's possible for a dominant player to simply buy up all of the available raw materials. In others, especially manufacturers and distributors of a large range of products, it is possible for them to establish contracts with retailers making the availability of their products contingent upon the retailers agreeing not to carry competitors' products. There are a variety of ways to compete in ways that don't involve offering better products or lower prices by manipulating the supply chain.

    But generally, they do it by filling the power vacuum left by a weak government. You end up -- as we did in the late 19th and early 20th century -- with large corporations paying their employees with scrip and having them live in company towns under the watchful eye of private security forces that ensure obedience through the threat of destitution or, in the case of organized resistance, through large-scale violence. Of course, this is often inefficient, so the next move is for corporations to gain control of the government using bribes, campaign contributions, and electoral fraud to establish a publicly-funded enforcement arm and to pass legislation erecting such high barriers to entry that competition is impossible, as was the case with the Big Three automakers until we let the Japanese in.

    You'll object that this is exactly what you're talking about, monopoly through government, but you're missing the point. Once private enterprises become powerful enough to substantially influence and co-opt the government, the distinction between government and business ceases to exist. Excepting only some of the mid-20th century European dictatorships, it is always business that subverts the government, not government subverting business.

    Supporters of true laissez faire don't claim that it is magical.

    Sure they do. They claim that people with enormous power and wealth will never be corrupt, and that once corrupted, they will not self-organize to increase their power and use it to subvert the entire social system to their benefit. They argue, just as the communists did, that human nature magically disappears in the face of anarchy, but of course only their new ideological anarchy: the original anarchy from which humans emerged at the dawn of history was apparently the wrong kind of anarchy to produce utopia. Those old humans were short-sighted, greedy, and instinctively driven to seek power over their fellows, but the new [insert bullshit ideology here] humans are all honest, fair, freedom-loving altruists who only want to put in a character-building day at an honest trade in exchange for a chance to compete in a free market.

    If that isn't magical thinking, I don't know what is.

    Contrast that with supporters of state control and increased regulation. To them, the government can fix anything.

    On the contrary, we do not.

    And that, ultimately, is the fly in every variety of libertarian laissez faire capitalist ointment: wealth is a competitive advantage. Even allowing for a certain fraction of businesses that fail due to bad decisions, success builds on success until there are only a few players left. Then the rational decision for those players is to simply divide up the market and fix prices rather than compete, and cooperate to ensure that the barriers to entry are too high for any new competition to arise. Nor does it get any better if those few players actually compete with each other, as the end product is inevitably a single victor, i.e., a monopoly.

    Capitalism just isn't self-sustaining. It's great while it's racing toward equilibrium, but once it gets there, it's like any other system that's reached equilibrium: incapable of doing any good. For capitalism to work -- as with perpetual motion machines -- there has to be an occasional input of energy from the outside. In the case of capitalism, that's trust-busting and various less dramatic forms of regulation. Without that, you have an ever-shrinking number of companies leveraging their ever-increasing power to charge more and more for less and less.

If I wasn't already dependent on it, I wouldn't even consider it for future development, and I am eagerly waiting for one of the forks to a) mature, and b) develop enough of a track record to risk depending on it for the long term, or c) to settle on one or more alternatives such as Postgres and/or some of the so-called NoSQL solutions.
