these things inside your blood and be quite happy about it. Just try to avoid thinking about the submolecular genocide raging inside your veins. And I wouldn’t mention the fact that the poisonous robots living inside your blood are the only thing keeping you alive, if I were you. (There are nice, padded places the police tend to bring you to if you say things like that out loud.) Oh, and definitely don’t dwell on the somewhat worrying prospect that if too many of these poisonous-drug-administering nanomachines were introduced into your body, just waiting for the cue to activate, you’d be basically walking around pre-murdered, just waiting for somebody to take a whack at the robot-filled poison piñata that is your body. So that Auschwitz-in-the-blood analogy from earlier still holds true. It’s just that this time, you’re the one in the showers.
Historical Tradeoffs That May Not Have Been Worth It

But hey, don’t start getting freaked out yet! This wasn’t even the part intended to scare you; it was just an example of some of the wonderful things that nanotechnology can do for you (in this case, injectable anticancer Nazi robots).
It’s very unlikely that the burgeoning field of nanobiotechnology will be reserved solely for medical uses. There’s a pretty standard, preestablished pattern of dissemination in place for new technology. At first, new tech is always reserved for serious uses, but before long it’s so commonplace that you have it everywhere. Take the internet, for example: It was exclusively a military network just over forty years ago, and now half the line at Starbucks is tapping into said former military network to check out grammatically impaired cats while waiting for their Grande Frappucino. So sure, nanobiotech is just for cancer treatment now, but maybe tomorrow it’s a flu vaccine and maybe a week from now it’s a pain reliever, or a subdermal sunblock, or maintenance-free contact lenses. But if it’s that commonplace, then why not go further? Why not a customizable, morphing tattoo? Or a permanent cell phone in your ear? How about a remote control installed in your brain? The potential uses are tempting, and the appeal is easy to see.
We’ve established that it will be inside everybody eventually. Then what? Even supposing that nobody abuses the technology, its very nature makes even the most benevolent intent potentially lethal. Take the respirocytes proposed by nanoexpert Robert Freita: They’re a harmless application, just a kind of artificial red blood cell that pumps oxygen more efficiently and more stably than the natural equivalent—236 times more efficiently, to be precise. Because of this dramatically heightened performance, they would be invaluable in treating disorders such as anemia and asthma, or simply to oxygenate the blood for better endurance and performance in sporting events. In other words, they’re blood-borne nerd fixers.
However, with higher doses of these nanobots, their hosts could also be able to do things like hold their breath for several hours and run at a dead sprint for nearly twenty minutes. And that’s great! How many of you would want to be able to do that? Now, how many of you want anybody else to be able to do that? Go ahead; raise your hand if you want sociopaths who breathe underwater, sprinting rapists, and serial killers who never tire.*
*Put your hands down, aspiring serial killers and rapists. Your vote does not count here.
Not to mention the worrying fact that these machines are by no means human-specific. The respirocytes take a kind of frat-boy approach to blood: If it’s warm, it needs to be pumped. No further distinctions need to be made. Also of concern is the fact that their durable outer shell and self-sustaining programming make them seriously hardy devices, easily capable of
