US researchers have developed the world's smallest fully programmable robots, on a scale of 0.2-0.5 millimeters, the same size as microorganisms that cause diseases like dysentery and schistosomiasis. (futurology.today)

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.

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.
