"Nanotechnology is a branch of science that deals with particles 1-100
nanometers in size. Experts believe possible dangers of nanotechnology lie in
how these tiny particles might interact with the environment, and more
importantly, with the human body. Billions of dollars are being spent to
incorporate nanoparticles into products that are already being marketed to the
public; when this investment is compared to the the comparatively scant
research into nanotech health issues, some scientists become concerned."

"If potential benefits of molecular nanotechnology (MNT) sound too good
to be true, there is one caveat — the potential dangers of molecular
nanotechnology. When nanofactories can arrange atoms into structures — playing
with the building blocks of life itself, or in this case nanoblocks --
theoretically anything allowable by the laws of physics can be created fast and
cheap. Requirements include a few square feet for the nanofactory, the
software, and an electrical outlet.
Criminals, terrorists, disturbed individuals, governments, and antisocial groups of all stripes would be incredibly empowered by such technology. Additional potential dangers of molecular nanotechnology threaten the economy, environment, human rights, and world peace. The rush to gain supremacy through nanoweaponry could lead to a new arms race, while attempts to stranglehold the technology would likely result in independent, covert development. Unilateral, "open-source" international cooperation is another option that runs its own risks, and control in the public sector could lead to inequitable benefits and an Orwellian society. The probability factor of certain potential dangers of molecular nanotechnology will be higher than others, but all are possible within a scope of circumstances that, without prevention through forethought and planning, could feasibly come to pass. Some dangers cannot be discounted even with said planning, while others can reasonably be assumed to be goals of recognized subversive elements."

Would this be plausible?
Is there already an actual nanobot in practical use?
or at least a robot that is as small as a pebble?
We can not just live the way we live now? Is not that good enough?

Happy New
Year:)
The dangers are real, although probably not much different than the danger of chemical weapons which already exists. As long as the potential effects of misuse of nanotechnology are limited in scope we can deal with it. The bigger issue is what happens when someone designs a self-replicating virus-like nanobot akin to biochemical weapons which can spread and wipe out whole populations of people? Hopefully that wouldn't be neither easy nor cheap, so it couldn't be done by just anyone. But where there's a will there's a way and we can't expect everyone to simply agree in good faith to refrain from developing such technology.
ReplyDeleteUnintentional consequences of nanotechnology seem more manageable, we've been dealing with similar problems like pollution and food safety.
The 9 parts of the video never got around to discussing nanotechnology but it was interesting nonetheless :)

Delete1. Would this be plausible?
ReplyDeleteI think it's slowly entering into our world. If somebody working with nanotechnology, i think that the military may already have some advanced stuff :)
2. Is there already an actual nanobot in practical use? or at least a robot that is as small as a pebble?
I think that there is not yet practical nanobots,but who knows..., maybe army.. :). If somebody has ever been built nano-machines, it will have many uses. For example in medicine, nanobots may be useful for the identification of cancer cells and destroy them. Nanobots injected into the body would be able to significantly extend the humans life by eliminating disease and maybe even give us immortality.
3. We can not just live the way we live now? Is not that good enough?
The live of our ancestors was good too. They simply did not know that they lives can be better and we are in the same situation :)
4. What are the Possible Dangers of Nanotechnology?
Probably a lot of. Omitting military action to eliminate other people, I think there is similar to GMO, we will know effects a few generations later.
5. Your opinion?
Currently Nanotechnology is very fashionable and promising science department. I think now would be a lot of practical uses of this technology, like Machine to do "everything". If we can interchange atoms and molecules, we can order nanobots to do everything what we want :)
Would this be plausible?
ReplyDeleteYes. I believe that nanotechnology is about to begin. Scientists start to be able to control more and more in nanoworld. As with all powerful technology there are dangers and positives. We must choose.
Is there already an actual nanobot in practical use? or at least a robot that is as small as a pebble?
It is possible that there is one with some limited functionalities and not yet in wide public.
We can not just live the way we live now? Is not that good enough?
It surly good enough but do not expect that there is any stop signal for a human curiosity. It may go with millennium long cycles that people invent something that later they use to destroy themselves in 99%. The remaining 1% will go through and would need to start again – there is a place for a simple nature close life eras.
What are the Possible Dangers of Nanotechnology?
Human extinction, super human race emergence
Your opinion?
Inevitable as all other parts of science. We must keep the common sense as our lead.
Most of the modern technologies cannot clearly be classified in terms of good or bad. Gunpowder can be used both for fun (just a few days back we could all see the sky brighten up with fireworks) or for killing others.
ReplyDeleteDevices based on nanotechnology also could be used in both ways. On one hand, it could be used to improve the quality of life for all the people that could afford such devices, but at the same time this could lead to serious problems. Some of us already pointed out the biggest threats: biochemical weapons, new diseases, viruses, etc.
Moreover, I do not think that we can do anything to stop this technology from progressing and that if it becomes accessible, we just need to try to manage it as best as possible so that it would not be used in the way it is not supposed to be.
Would this be plausible?
ReplyDeleteAs I have mentioned in earlier posts everything is... but nevertheless I think even if this comes to be it will still be a long while and we may not live to see it.
Is there already an actual nanobot in practical use? or at least a robot that is as small as a pebble?
It depends how do you define robot/nanobot, there are already a lot of electronics devices that is small and is able to perform certain tasks. Although they may be simple, they are foundation to more complicated matters.
We can not just live the way we live now? Is not that good enough?
I think such approach would stop evolution :D (really !)
What are the Possible Dangers of Nanotechnology?
I am not the specialist in this field but I think does mentioned above sounds good, namely:
power to create things which can harm others...
Your opinion?
I think that nanotechnology as almost every technology could be used as well for good and bad. Taking for example simple case we can take a pen and write a book, but on the other hand we can put that pen in somebody's eye :) Maybe a little drastic example but I think it gives a little bit about what I think about that. As stated before withholding inventions and technological progress here is rather not an option, it is rather about controlling how should we use it.
I agree with Grzegorz K. that “Most of the modern technologies cannot clearly be classified in terms of good or bad”. We need additional researches for evaluating value of some current discoveries.
ReplyDeleteI don’t know any nanorobots which I tell you about. Maybe US army owns such things, maybe a little greater than a pebble or even smaller - I don’t know.
I agree with Artur’s opinion about living. Now I don’t live in a way which I planned 10 years ago so I’m already (although partially) prepared for nanotechnological revolution ;-).
I think that danger starts when we can’t control our technological discoveries (or when we think that we control them but we don’t control in fact). But humanity can say "stop" as armament race showed so I look at future optimistically.
My opinion about nanotechnology? - such nanotechnological layman as me can’t predict future of this discipline. In my opinion some directions of science development are attractive and hopeful until somebody will discover something more attractive and hopeful. But some specialists gave Noble prize for nanotechnological discoveries – so it should have a quite bright future.
Would this be plausible?
ReplyDeleteI think yes, this is very powerful technology which is already use e.g in some drugs.
Is there already an actual nanobot in practical use? or at least a robot that is as small as a pebble?
In fact really I don’t know
We can not just live the way we live now? Is not that good enough?
I suppose not, world is changing everything. Not because something is wrong simple we want better life. Thinks like nanotechnology will help to develop many area of our live
What are the Possible Dangers of Nanotechnology?
I don’t know maybe some military weapon ?
Your opinion?
In my opinion nanotechnology has got huge potential. In next few years we probably will see it, personally I would like to see new drugs for cancer or another incurable disease.
Would this be plausible?
ReplyDeleteI think that yes.
Is there already an actual nanobot in practical use? or at least a robot that is as small as a pebble?
It can be I think that nanobots are use by army or if not they are working on that and maybe they do some test.
We can not just live the way we live now? Is not that good enough?
I think that we should work on new technology which will help use we can't stop on that what we have now. If 100 years ago people stop thought about new inventions we won't be here where we are now:)
What are the Possible Dangers of Nanotechnology?
It depends how we will use it if we will use it to make war it can be very dangerous but if we use it in right way it can help many people.
Your opinion?
I think that nonotehnology is good opportunity to help people in the future but it need to be use in right way.
