Trendal just brought this up on another thread and I was wondering what other people's opinions are on this question (I'll leave it as broad as possible):
What do you see as being the risks of continuing the development of nanoscience and how serious do you think they are?

I don't think there is any chance we can ponder to any meaningful degree, but I'll bite and give me opinion.
Risks? I think the risks will be just like any other technology. THe bigger it gets, and the more involved it gets, the more chance there is that someone will die. When it happens, people are going to get really upset and legislation will be passed, stunting it's growth and slowing science's ability to improve it to a point where it's safe.
Maybe in 200 years will we be able to fathom the grey goo scenario

Well let me first off say that I don't think any heavy regulation or outright ban of nanotech research is a very good idea. On the contrary, it is probably a horribly BAD idea.
The risk is not so much with nanotech itself, but with self-replicating nanotech. In this scenario, most of the risks of bio-terrorism are present as well as some added risks that nanotech carries itself.
Imagine if terrorists got their hands on even a SINGLE self-replicating nanodevice. That single device could easily, when given the raw materials, begin to replicate. Replication will most likely be faster than biologic replication, possibly MANY times faster, so it would not take long to turn that single nanodevice into a LARGE cloud of devices.
Someone could design a nanodevice which is self-replicating and which uses DNA molecules in the replication process. These would then seek out and destroy every single DNA molecule they happen to come accross - not too good for us biological types

Once, men turned their thinking over to machines in the hope that this would set them free.
But that only permitted other men with machines to enslave them.

I can see a future world war based on nano-weapons. The terrorists release one, the civilized world releases countermeasures, and so on until the Earth is a technological wasteland of competing nanobugs. Depressing scenario...

Here's a good sci-fi piece written about the possibility of a nanotech "disaster". Good read!

There is a huge misconception out there about "self-replicating" nanotechnology and "nanomachines". Self-assmebling and replicating systems have existed for a long time and much is known about them. They are used to deliver drugs to targeted sites in the body as well as for materials engineering.
I think the latter will have the largest impact from nanotechnology. We aren't talking about systems that can think for themselves or something equally ridiculous, they are just molecular systems that are designed to assemble into a more organized form under the right conditions...like an endothermic chemical reaction.
Everything else is just science fiction.

I dunno, as we learn to better manipulate tiny assemblies of molecules into more and more complex self-replicating systems, Trendal's dooms-day scenario might eventually become plausible.
Everything else is just science fiction.
Science fiction has a history of becoming science.
Maybe I'm just being pessimistic...

Yeah no kidding lol. Science Fiction has a way of becoming real given enough time.
I can see a terrorist totally wanting to destroy all of mankind with a self-replicating goo that feeds off carbon or something like that. That would hurt a bit =/

Well, I never got around to saying what I wanted to say on this subject, but I just found some cool lecture notes and such from a course at the University of Wisconsin-Madison entitled "Nanotechnology and Society":
Nanotechnology and Society
There is also a collection of funny and not-so-funny nanoscience jokes.

nanotechnology is nothing new... nature is built from the nanoscale up, we're just found new ways to study and mimic these processes. I work on nanomaterials so my opinion is a little slanted.

I also work in the field, and I agree with you
