To that end, IRV has several advantages: First, it's easy for anyone to understand how it works, which is extremely important -- people won't trust a system they can't understand, and they won't adopt a system they don't trust. Second, it has a decent amount of political momentum behind it already, with IRV already having been adopted in San Francisco, and being seriously considered in Vermont and elsewhere. Other methods would have to start from scratch, which would mean more elections held using the current, inadequate plurality system.

You can argue all you want about the "benefits" any technology has, and that resistance to the "advances" it has brought are Luddite. That doesn't change the fact that there are more poor, starving, diseased people on this planet RIGHT NOW than there ever have been at any one point in history.
That's only because there are more people alive now than ever PERIOD. As a fraction, the portion of starving and/or diseased people is lower now than ever, as evidenced by the doubling of life spans in the thrid world, and tripling in the indistrialized world. That much is indisputable.
"Science" has had nearly three hundred years to show how it can benefit the bulk of humanity, and yet most people--outside of those who would ever read this forum, sadly, still live lives of quiet desperation, with little or no voice in the direction that "science" is taking them and the rest of us.
First, you assume that someone who doesn't live in your world is miserable, which is not necessarily true. Second, coming to America and studying SCIENCE is a very common way for people to come from very poor areas and learn skills to improve their lives. Frequently these people go back to their homelands, trained, to make their nations better.
Since almost every modern technology emerges out of militarism--whether as an advance of it or in response to it, and since we might be able to agree that killing entities other than ourselves for dubious reasons determined by the upper class is less than optimal, the jump from nanotech being a scientific endeavor to an evil pursuit is not that great of a leap.
That was true 500 years ago but not now. The drug industry (and non-combat related biotech) is the largest growth industry right now. Communications is not far behind. Neither industry arose from military (Alexander Grahm Bell's telephone, germ theory, viral vaccinations all arose from civilian research). As far as nanotech=evil....where is the first world committing genocide? I don't know where these myths come from, but not anytime in the last 50 years.
Nanotech research, in my opinion, should go forward, but it needs to be absolutely open, WITHOUT a market-driven force propelling it (the same applies to genetic engineering, as well.) I realize that is a pie-in-the-sky requirement
Pie in the sky is an understatement. People are inherently lazy, and don't want to do anything unless it will also benefit them at the same time. Does that suck? Yes, but that means if we want things to help people, we have to help the helper at the same time (say, financially). As for open, I agree, and that's the role of the peer-review publication system. But the market driven force has to be there or nothing will come of it.
What is wrong with using the loaded word of evil in describing those who do what they want without consulting me when I am directly affected by what they do?
Well, it's a bit arrogant if you define your sphere of "being affected" so broadly. Other than intellectually, you haven't been harmed in any way that I can see.

He makes some arguments about deregulation generally which I regard as pretty vaccuous. Requiring companies to use the best available technology encourages other companies to research it and then force the first company to buy.
Anyway, to answer your question - the reason we'd want to regulate nanotechnology is because it might be dangerous. The thousands and thousands of completely harmless applications of nanotechnology - basically just material science - don't need any special regulation. It is only when the nanotechnology begins to resemble a living organism that the need for regulation comes into play. The fear, and it is remote but still legitimate, is that someone would make tiny robots that would breed out of control and become a social problem.
He points to biotechnology (which is basically unregulated, except in so far as it is also medical) as a big success. It has been - SO FAR. As yet, we have had no environmental catastrophes resultant from biotech, and the medical errors have been fairly small in scope, and would have been prevented if existing laws/procedures had been followed.
However - that doesn't mean that what we're doing is safe. It means, either, that what we've been doing is safe OR that we've been lucky. Personally, I think biotech is "pretty safe," but that agro-biotech (Monsanto, in particular) has too much free reign.
In any case, until we have a better idea of what nanotechnology will actually be like, it is premature to discuss regulation to make sure it is safe. Banning nanotechnology outright would be impossible for the reasons he has mentioned. Banning specifically self replicating nanotechnology, though I think it inadvisable, WOULD be feasable. Regulating self-replicating nanotechnology is probably desirable.

The wonderful thing about being a human being is that we can choose what to do and what not to do. I can choose to stop at a crosswalk, or I can choose to plow through a crowd of second-graders.
Your argument is basically that it's foolish to stop. Somebody out there is going to plow through a crosswalk anyway, so we might as well get in there and figure out how to use it to our advantage. If you think I'm misrepresenting your argument, maybe you'd better go back and read your own words again. "New technologies will come and be used whether we like it or not. Cloning will occur whether we ban it or not." You say this as if there were no moral or ethical aspect to it whatsoever, and that's simply not true.
Some things just should not be done. If you're an amoral person-- and your post, especially the part about "religious paranoid idiots," certainly seems to suggest that you are-- then you probably reject this assertion on its face. If that's the case, I won't bother trying to convince you otherwise. (My opinion is that people with no sense of morality or ethics at all are mentally ill in a way we just haven't figured out yet. Nothing personal; it's just a theory.)
So let's just take as given that you believe, at least on some level, that some things are just morally wrong, and should not be done. I'll take an easy example: we have the technology to safely and painlessly sterilize people who have congenital mental or emotional defects. Such people obviously aren't capable of making rational decisions about reproduction by themselves, due to their defects, and we have the technology to do it for them. Should we do it?
The correct answer here is no. No person has the right to do something that drastic to another without just cause and without that person's informed consent. So some things are simply morally wrong. (You don't have to agree, but you do have to have an opinion. Not having an opinion on this question means you have no ethical sense at all; in that case, just stop reading, because I'm not interested in arguing about the nature of ethics with you.)
Is cloning wrong, morally, ethically, pragmatically, or for some other reason? How about stem cell research using in vitro embryos? I don't have answers to those questions, but it's vitally important that we ask them. Because the answer might just turn out to be yes. And if it is, and we didn't bother to think about it before acting, the results would be tragic beyond any justification.
When you were small, your parents-- or somebody, surely-- taught you to look both ways before crossing a road. This is the same principle. Should we ban cloning, or nanotechnology, or any such thing? I don't know. But I know, beyond a shadow of a doubt, that we must ask the questions, and we must have the arguments, because the risk of acting without forethought is far too great.
Also, nice to know there might be millions of natural deadly bacteria in it.
Jellies and jams, and other canned and jarred goods, are inherently pasteurized. The jelly is poured into the jar while still quite hot-- over 140 F-- and the jar sealed. No bacteria in a jelly jar unless the seal is broken. You don't have to be afraid of the jelly jar any more.

As for assuming he is amoral just because he feels strongly against the religious right is just plain foolish. You are confusing morality and ethics with religion. They are two totally separate things. I consider myself a moral person, but I don't want other people to try and force THEIR morals upon me, which the religious right has a tendancy to do.
The questions you ask are the kind that will probably never have an answer. We have been trying to decide exactly what constitutes "life" (not biological life, but conscious life) for thousands of years, if not longer. I do agree, the risk of acting without forethought is there, but also there is the risk of not acting.
There is no universal answer to questions of morality, as morals vary from person to person, society to society. Myself, I don't find pornography morally offensive, but I know a great many people do. In America, we do not find the sight of a woman's legs morally offensive, but in Saudi Arabia, they do.
The basis for applying these morals gets especially sticky in the areas of 'altering life' (nanotech, gene therapy, even abortion, though that's a whole other matter) because we don't even know what makes "life" exist. Yes, we've sequenced the genome, but without the so-called "spark of life," all you have is a lifeless, gene-sequenced body. What actually creates life? Many would say God. Others would not. But should we not at least try to find the answer, or should we just throw up our arms and say "It is the work of God!"
That is simply ignorant.

Actually, anything that's morally wrong is simply morally wrong. That's because morality depends on one or more fundamental axioms provided from outside of the moral system. Every culture-- big or small-- has some set of moral axioms, and though not every member may agree on them, they can be used to construct childishly simple moral arguments. Capital punishment, for example, is morally wrong because the question of the time of a man's death is a choice that only God can make, and choosing to kill a man is to place oneself in the position of God, which is blasphemy, which is wrong. That argument only holds water if you accept all of the fundamental assumptions-- that God exists, that only God has the right to choose when a man dies, and so on-- but if you do, the argument is trivial.
Ethics, however, are more complex, because an ethical system is expected to be internally consistent, starting with no external axioms at all. An ethical argument against capital punishment might be that no one can predict what a person might do in the remainder of his natural life, so ending that person's life may be depriving society as a whole of a greater good. That argument, which many people find to be pretty compelling, doesn't depend on any unfounded assumptions, so it's more complex, but it requires less... oh, faith, I suppose, for lack of a better word.
Some people, though, reject all concepts of morality and ethics. These people, as I said before, are basically broken in my opinion. Arguing morality or ethics with them is a fool's errand, because they reject the prospect that one should act based on moral or ethical choices. Talking about ethics with a person like that is enough to make you want to jump off the roof, so I just won't bother.

As far as your example of an "ethical" argument against capital punishment, it makes the assumption that a "greater good" exists and furthermore the assumption that "we shouldn't do things that deprive the society of a greater good" and also that "no one can predict what a person might do in the remainder of his/her natural life" and that "if no one can predict what a person might do, then that person may do things which contribute to the greater good" etc etc. You may disagree with the set of assumptions I've extracted but I think my point is clear.
Pretty much all human knowledge and reasoning is either based on assumptions that are just taken for granted, or inductive truths that are never 100% guaranteed to be true. This fact is somewhat intellectually jarring, but we seem to go on figuring things out about the world just fine nonetheless.

Well, yes and no. In the strictest possible sense, you're right. When making ethical judgments-- which are, at their heart, value judgments-- you have to start with some basis for value. There has to be an explicit or implicit "X is good" in there somewhere. For example, in order for my previous trivial example of an ethical argument against capital punishment, you have to start with the implicit assumption that a benefit to society is a good thing, and that depriving society of a benefit is to be avoided.
But there's a significant qualitative difference between starting with "avoid doing harm" and starting with "God exists and he has given us rules by which to live." One starts with a proposition so obvious that it requires no rationalization. The other starts with a proposition based purely on faith, for which no rationalization is possible.
How do you prove that 1+1=2 without reference to anything external?
That's exactly what Whitehead and Russell did in their Principia Mathematica. (Not to be confused with Newton's book of a similar name.) They started with absolutely nothing and developed the principles of symbolic logic, sets, and relations, then finally got to cardinal arithmetic at the beginning of volume 2. So it is definitely possible to reduce something as fundamental as arithmetic down to first principles. It's not easy, but it's possible.

Reconciling these disparate doctrines is a job for a person with more patience than I have.
The blasphemy argument is just one example of a moral case based in Biblical principles. You can flip through the Bible to find material to support any argument, any position at all, on this matter.
Oh, by the way, your ethical argument against capital punnishment is faulty because the person could also do unspeakable things if they live.
The chance that a person, duly incarcerated, can commit a crime is slim enough to be acceptable to many people.
At best the argumenbt as stated is a wash and therefore inconsequential.
Not at all, because the argument is based on the idea that it's better to err on the side of caution. A person imprisoned for life can still do good things. A person executed for his crime is lost forever.
There is no reason that any person that believes in the Bible should have anything to do with the abortion issue.
But the Bible should not be taken literally on matters about which biblical authors knew nothing. The concept of the "breath of life" is not meaningful in the context of what we now know about human development. Few could argue that a baby is not just as alive ten minutes before it is born as it is ten minutes after.
It's one thing to use the Bible as a source for moral guidance, for religious teaching and doctrine, for history, and for a whole host of other purposes. It's quite another thing to use it as a science textbook.

Great idea. At this point, they're not self-assembling any more. This is, in fact, the only solution to the problem.
Of course, if the assemblers are able to self-assemble, it's quite likely that they will be caused to self-assemble by some external factor sooner or later. So the only safe way to apply this solution is to make the assemblers physically incapable of assembling themselves.
