In most people’s sci-fi nightmares about robots trying to wipe out humanity, the robots tend to be big. But wouldn’t they be more deadly if they were tiny? 0.2-0.5 millimeters is bigger than bacteria or viruses, but it’s the size range of many single-cell protozoans.

That possibility is bad enough, but we’d better hope no one figures out how to make these things self-replicating. Think that sounds far-fetched? Evolution figured it out with single-cell organisms 2 billion years ago, and they haven’t faltered since.

World’s smallest programmable robots perform tasks: Microscale swimming bots developed by U-M and Penn take in sensory information, process it, and carry out tasks, opening new possibilities in manufacturing and medicine.

    Great. Microscopic robots that could be programmed to kill people. I’m sure that won’t have any unintended consequences when governments us this for assassinations.

    The “brain” that is in these robots is incredibly simple and does not have the capability to learn. While it feels like tech is breaking boundaries every day, having any serious amount of computational power that simulates learning at this small of a scale is incredibly far off. The fear mongering is not necessary.

      I wasn’t thinking about the little robots figuring it out. I was thinking of humans designing it, and releasing it (perhaps accidentally).

        And look at the havoc that relatively simple but communal organisms can wreak (ants),

        Then there are bacteria, viruses, and other single-celled organisms.

        All one would need to do is replicate itself and produce a toxin.

    your scientists were so preoccupied with whether or not they could, they didn’t stop to think if they should.
