Are there any truly autonomous machines which don’t require a human to monitor?
Lots. Toasters, refrigerators, robot vacuums, thermostats, smart home lights, etc.
The reason why self-driving cars are extra tricky is both because they have a much more complex task and the negative consequences are sky high. If a robot vacuum screws up, it’s not a big deal. This is why it’s totally irresponsible to advertise something as having “full” autonomy when the stakes are so high.
Yeah, got a small delivery car in my country that drives the streets fully autonomous. It is used to deliver groceries to a distribution point.
It was kind of hallucinating to see it drive past. Since the car has a sort of cockpit, but it is too narrow to seat any human.
It is currently limited to 25 kph, and someone supervises it remotely at all times and can intervene. Just to be on the safe side. Although that rarely happens.
The main reason it can do this is because it always drives the same route.
