    I would say it's potentially confusing, but not necessarily misleading, if you put it in context. I think it's reasonable to talk about "memory access frequency" in terms of MHz, i.e. memory access cycles per second.

    The "cycles" are logical, in that electrically they're actually half-cycles, but if you want to do calculations involving memory bandwidth, MHz is actually the right unit - since the multiplier (2) has no natural unit.

    And personally, as far as I can see, most of the much vaunted human "intelligence" is "just dicking around with heuristics".

    The radical split between words and deeds certainly worries me, especially because it seems that politicians don't feel it necessary or expedient to be honest with their electorate.

    I agree, I don't like that. But I also think it's somewhat inevitable. The article recently posted here with the subject "On The Collapse of Complex Societies" has some interesting info which attempts to explain some of these societal behaviors. I liked this message.

    A little while ago, there was a South Park episode which proposed that the liberal/peaceful vs. conservative/hawkish sides of the debate were both necessary - the latter to get the dirty work done, and the former to act as a conscience and both temper the hawkish position, and as you say put a human face on it. (It was put a little more humorously than that in the episode.) It's not just that two different constituency's voices are being reflected, but that the two constituencies balance each other and are essential to each other. It's cynical and disingenuous on the whole, but perhaps effective.

    I'd be quite happy with everyone bluntly coming out and saying exactly what they think/mean/feel about an issue, but I have the feeling that game theory probably dictates against that approach in general, given conflicting self-interests and especially given human nature.

    None of this is to say that we shouldn't try to hold our politicians to high standards. But I think I'm a bit of a realist about that too.

    Thanks for the links.

    I don't mean to slight the progress made, and I also didn't mean to criticize all AI researchers.

    Perhaps a better way to describe what I was getting at is that there's an unfortunate feedback effect that happens with these advanced applications, where: researchers say things which excite the general public because they describe things that sound amazing and desirable; researchers notice said excitement and connect that with increased funding; researchers exploit excitement by attaching loaded buzzwords like "AI" to all sorts of vaguely related research projects. But what the public heard or believed initially, is never actually delivered, and what is delivered doesn't seem nearly as exciting as the original vision. If not for this effect, the first "AI crash" would never have happened.

    Of course, what I've described is to some extent how the promition of just about any project or product works. The difference with advanced applications like AI is that the ultimate end goals - which are often brought up as justifications for the work - are so far from achievability that expectations are dashed much more than usual when the projects finally reach some kind of fruition - if they ever do. Much of the audience then feels as though it was burned, and could care less about the fact that "real" AI is so much harder than any other software that's been developed to date. They simply perceive that what was "promised" was not delivered.

    Like public companies which learned to carefully manage their earnings so as to remain in line with Wall Street expectations, researchers in these fields need to be careful about expectations management if they're going to promote their projects publicly - unless they have something concrete they're going to be delivering in a finite and predictable timescale.

    I do think a term like "Cognitive Systems" is much less likely to suffer from these kinds of problems. Many things which could reasonably be called cognitive systems research could not, without significant qualification, really be called artificial intelligence research.

    The problem is actually largely self-inflicted by AI researchers, who have at various times used AI as a gee-whiz hook to justify all sort of research that are at best, peripheral applications of a weak form of AI. Even scientists pay a price for overuse of hype.

    "Real" AI would emphasize the "intelligence" part and be capable of, for example, learning the rules of a new game or process from a natural language description and trial and error, and then being able to perform said process. Anything less is pretty much just dicking around with heuristics.

    Anyone who ever claimed that machine vision or chess playing or voice recognition was AI, was either confused or guilty of the charge in the first paragraph above. Even before those things were first achieved, the people actually working on them had a pretty good idea of how they could be achieved without anything like what we normally consider intelligence - and they went on to prove it.

    I hardly think you can say that the software industry is 50 years old. That covers a period where software was typically included along with hardware, as well as a long period where consumers couldn't buy anything remotely resembling software, mainly because they had no access to machines which could run it. The law described by Phronesis arose from concerns about interaction with "the public". The first time "the public", beyond programmers and hobbyists, was able to buy software as an independent product would have been in the early '80s, making the consumer software industry a mere 20 years old.

    I think an important difference in the Balkans, compared to Rwanda, is that many of the countries who wanted to take action in the Balkans were direct or nearly direct neighbours, countries which could potentially be directly impacted in all sorts of ways by Balkan instability.

    Africa suffers from a vicious circle of not having countries with strong, stable economies, by Western or Asian/Eastern standards. Any intervention would need to be almost entirely from off-continent, with very little "local buy-in", even if the action were locally supported. The European NATO members picked much of the tab for Bosnia - because it was to their benefit. Action in Africa would be pure charity.

    So, sure countries act in their self-interest. There are no countries willing to act as a global daddy, willing to bail out any errant child nation regardless of the circumstances. Nevertheless, pure humanitarian considerations are an issue for many people, and you can hear that being discussed on the political stage in the US Congress and Senate, and in the British Parliament.

    Yes, I think lack of equal representation is a big issue, or any situation where political representation of citizens is severely restricted, as in Iraq.

    I'm not saying that's a sufficient condition for military involvement, but it does tend to be a necessary condition. It'd be much more difficult to justify invading a country like Iraq with the knowledge that the majority of its people are in full support of the country's policies. In that sense, the supposed moral issue is actually a strategic issue.

    But the full reasons for actions like the one in Iraq are always going to go a long way beyond any moral question, so I agree that trying to argue it on the moral question alone is misleading. In practice, the US doesn't act as a global policeman - it acts to serve its strategic interests (or other interests, such as the Halliburton balance sheet.)

    Or, even better, what if another country, which is governed by a direct democracy, feels that our country is controlled by two tyranical parties that don't allow people to express their particular views on a given issue [...] Anyway, this other country marches in, and forces us to change to a direct democracy. Is that legitimate?

    That could get interesting - if, for example, the two-party system was successfully being used to suppress attempts to move to a direct democracy, then you could argue that an invasion like that was "legitimate" - and subsequent history books probably would do exactly that. Of course, legitimacy is relative.

    Really, beyond the national level, where political representation via a voting system hasn't worked so well, this stuff is mainly about might making right. It would all be playing out very differently if the only global superpower was an Islamic-led state.

    I don't see a comparison with US drug policy, because the United States has a government elected by all its citizens, and is not restricting freedom of association, speech, and movement in order to prevent citizens from expressing their political views. It's not torturing and murdering dissenting citizens in order to maintain its policies. US drug policy is a "legitimate choice" of the citizens of the US. China or any other nation has no basis on which to interfere.

    In the situations in both Iraq and South Africa, the United Nations saw fit to impose sanctions and other mandates. Despite the ineffectiveness of the UN in general - or perhaps because of it - that's no little thing. It means the countries in question were doing something sufficiently obnoxious, that other countries could agree it was not acceptable.

    Besides, "interference" in South Africa by the US and everyone else (e.g. the UN) was limited primarily to economic sanctions. There were never any US troops on the ground in South Africa. The opposite, actually: the US supported South Africa in its military actions in neighbouring communist-backed states such as Angola.

    Apartheid is a legitimate choice that the people of South Africa decided to live with for a while.

It doesn't qualify as "legitimate" in my book.

    The involvement of the international community in South Africa was largely at the request of the leaders of the black community there. The African National Congress, for example, did a lot of lobbying internationally in order to focus attention on the problem. Without the resulting international pressure, the situation in South Africa would not have changed when it did.

    As such, the US had excellent justifications, from a moral perspective, for "waltzing in and shaking things up". They were dealing with a brutal and backwards regime which was oppressing the majority of the local population.

    Your post demonstrates the exact misunderstanding about SARS and containment of infectious disease that has led to the current unwarranted hysteria.

    The point about SARS is not how many people it has killed relative to something like your example of murders in Texas. Murders in Texas are not particularly contagious.

    The purpose of WHO's advisories is to limit the spread of a contagious disease. It's not really targeted at individuals to tell them that they may be in danger if they go to Toronto - the point is to stop the spread of the disease. However, the disease is ultimately spread by individuals, and to stop it spreading, you ultimately need to prevent individuals from acting as vectors for the disease. That means issuing advisories telling them not to travel to certain regions, and it means quarantining people who may be infected, even though you know that most of them are not.

    Unfortunately, individuals aren't very good at recognizing and respecting risks to a global population, and they tend to want to personalize it - which leads to the faulty logic that since the SARS risk to an individual travelling to Toronto is low, it is therefore OK to travel to Toronto.

    This is a little like saying that since my personal taxes are small relative to my country's total tax revenues, that I don't need to pay them. The point is that disease containment, like taxes, only works if everyone complies.

    BTW, the truth about Toronto specifically, as I understand it, is that its quarantine practices originally weren't up to scratch, and it allowed e.g. exposed health care workers to wander freely amongst the population - attending church, for example. It's at least partially these lapses in containment procedure that have led Toronto to have one of the largest SARS-infected populations on the planet, which is why it was slapped with a WHO warning. The warning is the result of Toronto's health care system and government not originally taking the problem seriously enough.

Sometimes, those negotiations give way to violence, in which case might can "make right". However, that's still very simplistic.

It's easy enough to come to agreement on certain basic things - the existence of a certain object, etc. But you don't have to go very far before you realize that in general, absolute truth is not only non-existent, but meaningless as a concept.

    One of the tests of a worldview is whether its adherents can live integrally - according to the consequenses of their views.

    Certainly. Human societies around the world exist as a result of millenia of negotiations with each other, both peaceful and violent, and negotiations with the world around them. If you want to take refuge in facts such as that it's an absolute truth that we need oxygen, water, and food to live, fine. But again, that's simplistic, and certainly doesn't get you anywhere when it comes to moral truths.

    Relativism collapses under its own weight. It cannot stand.

    In fact, it's the opposite. Millenia of thinking on this subject has invariably shown that absolutism cannot withstand the application of some simple logic.

    If you want to know how humans approach truth, a good starting point is Thomas Kuhn's "The Structure of Scientific Revolutions". It deals with scientific "truth", but it gives some good insight into the nature of truth and the search for it, in particular the unavoidable social aspect.

    You may claim to be a relativist, but I submit to you that you must live your life according to absolutes.
