Geological Manipulation

You’ve likely seen video games such as No Man’s Sky where you’re able to manipulate the world around you, quite literally, to develop specific things. Like if you want a mountain or hill gone or moved somewhere. This is something a lot of builders would love to be able to do. Nanotechnology could likely be developed to create powerful geophysical or geological manipulation technology. However, this is quite a dangerous thing for just anyone to have. It could cause issues such as earthquakes and even make nearby volcanoes erupt, even before they might normally do so. Obviously, this is not a good thing.

Time Travel

This might be considered the most theoretical on our list, but nanotechnology is clearly a potential asset to time travel. It is very likely that any time machine or any form of travel in space that affects time will use nanotechnology in some way. Naturally, there is always a risk that if we are able to somehow break the known laws of physics and go back in time, one could see how harmful that could be. Meanwhile, we know the laws of physics allow us to travel into the future at a pace much faster than what we experience on Earth. This can only be done in space, considering it involves only “spacetime” and does not connect to the time of any planet. Thus, nanotech could potentially cause a person to go into the distant future yet be incapable of getting them back to their previous time.

Teleportation

Yet another in the science fiction column for our list, teleportation is something many find to be theoretical for now. However, the laws of physics do not completely claim it to be impossible. Therefore, we cannot rule it out for the future. Most people believe that nanotechnology will most certainly be used for teleportation or some form of matter transportation. There are a lot of things to consider about this, however. First, there is the issue of how much energy it will take to teleport people anywhere. Second, it is the integrity of the matter one must consider too. The question most have is…will what I teleport away actually be what I teleported or a copy of it? This would then draw the question of…if I teleport somewhere, am “I” the one teleporting, or is it a copy of me?

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.
