Our problems and risks are huge, but so are our capabilities.
Scientists have inserted DNA-based nanobots into a living cockroach, which are able to perform logical operations. Researchers say the nanobots could eventually be able to carry out complex programs, to diagnose and treat disease.
…
The nanobots can interact with one another, and were shown to be able to perform simple logical operations, for example releasing a molecule stored within upon command. Or, as the researchers put it: “The interactions generate logical outputs, which are relayed to switch molecular payloads on or off.”
