Security & Surveillance

Clearly, beefing up our current security and surveillance systems will be a big improvement. Nanotechnology can be great for this as it will allow us to properly secure our homes, businesses, and even national borders. The issue is the ethical side of this, which most people do not consider when it comes to this field. For example, sensors using nanotechnology could be used to monitor a person’s actions and movements. This is a violation of their personal privacy and can be abused. Sure, if the police are trying to find a criminal then using this improved surveillance or sensor systems will be useful. However, one has to wonder how much it’ll be used. Will there be any safeguards in place to protect people from this type of technology, especially from those seeking to abuse it for control?

Nanotech And Human Health

When nanotechnology is used, and it is likely to be used quite a lot, there is a lot to consider. How much is too much, in this area? There is a possibility that nanoparticles or other nanomaterials could be inhaled, ingested, and even absorbed through the skin. If this occurs, one could be harmed by the toxicity of these nanomaterials. Many believe due to the small nature of these devices, things such as a technological super virus could be deployed by enemies. Due to the ability to control this virus, unlike actual viruses, we’d have a health nightmare that could wipe out entire regions. Something that no vaccine could cure or help us to prevent/help us through it.

Unintentional Or Accidental Release

Again, there is a lot that nanotechnology can do for us. However, there is just as much we have to worry about too. Since nano-materials have different physical, chemical, and biological properties than their larger counterparts, problems could exist. For example, we know we should avoid highly radioactive materials and there will usually be signs up telling us where they are. Yet what if you could come across the exact or higher radiation as a place like Chernobyl but in a small nano-size piece of technology? There is also the possibility that nanotech could accumulate living organisms and interact with the environment, both of which could have massive impacts on the world. We should not just use nanotech because it is there and we must evaluate all potential issues before they become problematic.

The Dangers Of Self-Replication

Nanotechnology might be incredibly helpful but what about the problem that many worry about most when it comes to nanotech? It is possible that nanomachines could self-replicate, which might be their intended design. This might be done as a way to “heal” armor or infrastructure to avoid the need to buy new materials. However, if this got out of hand and the nanomachines begin to replicate uncontrollably, we have a huge problem. These machines would begin to consume all matter on the planet just to keep replicating. While “technically” possible, these machines would have to overcome a lot of physical, chemical, and biological barriers that they are likely incapable of doing. At least, as far as we know as of this writing.
