Questioning the dangers of nanotech in a generic way is meaningless. Every living thing in the world is made of nanotech. It is nanotech that has come about by evolution, but the principles are the same. Some of the nanotech is good for humans, like DNA and the abilities of cells to create proteins and some others are not so good like viruses.
Inevitably some things that humans create can be good for us and others that aren't, but that goes for things of all scales.

Michael, this article is not questioning the dangers of nanotech in a generic way. On the contrary, it treats very specific cases. If you read the last paragraph, you will learn that shorter nanotubes don't seem to be dangerous. Every application has to be tested separately, a generic treatment is useless - because of the reasons you mention.

So then what is your point? Skip the testing? Because we're all made of nanotech? We are all made of chemicals, too, but I am happy there is at least some regulation that tries to prevent the release of man made chemicals that are harmful.

Great article and very true! It's scary that manufacturers still choose to use a material that they know is harmful, just because it is cheaper. It makes you wonder what other dangerous materials are in the products we purchase.

Why such an alarmist and pessimistic article? The asbestos industry knew the danger of of the material many decades before it's use was banned, and done nothing to warn those using it of the dangers. Because of their actions a very useful material that can be used safely, when precautions are taken has been banned. There is a danger the same could happen with useful nanotechnology, if the mislead the public as well for profit. I have no doubt nanotechnology can be safe when, precautions are taken. I do have my doubts if the nanotechnology industry can be trusted. Given the example of the asbestos industry and the Genetically Modified Organisms industry. All the assurances given to the public by the GMO industry turned out out to be false. In the end must choice does the public really have other than go with the flow? Now that I'm at the end of my spiel, I see why the alarm and pessimism.

And now they want us to EAT nanotech stuff;

Another potentially risky way to allow us to continue our overindulgent way of life...
