Michael Belfiore in Aeon:
Robots in the real world usually look nothing like us. On Earth they perform such mundane chores as putting car parts together in factories, picking up our online orders in warehouses, vacuuming our homes and mowing our lawns. Farther afield, flying robots land on other planets and conduct aerial warfare by remote control.
More recently, we’ve seen driverless cars take to our roads. Here, finally, the machines veer toward traditional R U R territory. Which makes most people, it seems, uncomfortable. A Harris Interactive poll sponsored by Seapine Software, for example, announced this February that 88 per cent of Americans do not like the idea of their cars driving themselves, citing fear of losing control over their vehicles as the chief concern.
The main difference between robots that have gone before and the newer variety is autonomy. Whether by direct manipulation (as when we wield power tools, or grip the wheel of a car) or via remote control (as with a multitude of cars and airplanes), machines have in the past remained firmly under human control at all times. That’s no longer true and now autonomous robots have even begun to look like us.
