Very cool trick, but got to hate the typical marketing BS. "You can imagine these snipping up tumour cells" How would these dumb devices be able to navigate the human body and correctly identify tumour cells? How would they actually destroy the cells in a clean an effective manner? We are still a fair distance away from the (gloomy or glorious?) vision of true nanotech.
Under any circumstances, would you accept implementing Microchips in your body? 1- Yes 2- Never 3- Wait and see 4- Will be forced by governments 5- Others
