The scary truth of nanotechnology

The idea of cyborgs have been around for decades, now however with the recent advances in nanoscience and nanotechnology we are becoming closer to being half human and half machine. Apparently nanotechnology could be put into the bloodstream and whenever you are ill. It scans what is causing you to be ill and then calls for a cure. This scares me.

Nanotechnology currently is in our smartphones as this is what allows them to be so thin yet do so much so quickly. Nanotechnology is also in tracking devices and other small bits of modern technology.
Nanotechnology is 1 billionth of a metre (that is small).

A good example of something which uses really small technology (maybe even Nanotechnology is the Memoto Lifelogging Camera, you wear this tiny box on the top of your shirt then it takes a photo every 30 seconds and puts them in an app for you to look at. It also takes your GPS location for the photo so you know where the photo was taken. This technology is currently on kickstarter.com, it was originally trying to make $50,000 however that sum has been tripled by avid investors.
