how can nanotechnology be one of the doomsday things that could extinct humans?
Question by Ripcity-zen: how can nanotechnology be one of the doomsday things that could extinct humans?
i’ve heard the nanotechnology is one of the hazzards of the future that could spell the extinction of the human race, much like nuclear war or comets and asteroids hitting the earth. how does the technology figure into it? what kind of things would come of it that is dangerous to us?

When people talk about that sort of nanotechnology, they’re usually referring to nano-robots. If they were able to break down matter and use it to replicate themselves, they could pretty much devour everything on the surface of the earth.
It’s just science fiction, anti-intellectualism, and fear-mongering, though. That sort of nanotechnology is *very* far away if it is even possible at all. Real nanotechnology involves constructing very tiny structures. One real application is carbon nanotubes – they could be woven into thread stronger than spider silk, yet lightweight. Another real-world application is in cancer treatment – where chemotherapeutic agents are encapsulated in microscopic shells that release the medicine in the vicinity of cancer cells (sparing the rest of the body).
Real-life nanotech poses almost no threat, beyond “this nanotech substance might be poisonous if you eat it”.

your question doesnt make sense… but nanotechnology is on the nanoscale, manipulating materials at this level is a hope for the future of science to create better, smaller and more efficient technology. Im sure i read in multiple websites that the household computer with all its specs can be made to be the size of a bacteria. But nanotechnology is a broad feild,

and also disadvantages i can only think of the ‘grey goo’ thoery, which is totally stupid, but go for your life,

bear in mind the date of the websites as future ambitions may be slightly unrealistic by todays standard, or nanotechnology may have developed since then. best of luck.
