Most computer mouse devices today are “optical;” they shine a light on the working surface (the desktop or a mouse pad) and use the reflected light to determine the speed and direction of the mouse’s motion. Earlier versions were mechanical, incorporating a trackball whose direction and speed of rotation was converted into electrical signals indicating the motion. (Mouse trackballs also had a habit of picking up dust and lint that interfered with the mouse’s operation. The optical mouse was a major improvement in this area.)

Here in the 2020s, we may not (yet) have cars that fly or general-purpose robots that are autonomous and clever, but we do have billions of network-connected sensors, actuators, appliances, and other devices.

Consider the following fictitious review of the 1999 film The Blair Witch Project:

The Star Wars canon has medical droids playing a prominent role in autonomous diagnosis and treatment of injuries and illnesses. How cool would it be if even semi-autonomous systems could handle routine diagnoses and treatments, freeing doctors and caregivers to focus on more challenging cases? Well that future is a little closer to reality than some may think!

Humankind, it seems, has for a long time been fascinated with the idea of machines that can mimic the human capabilities of thought, intuition, creativity, problem-solving, and communication. From the chess-playing Mechanical Turk of the 18th century (which was actually a clever and elaborate ruse) through the ELIZA computerized “psychotherapist” in the 1960s and any number of sci-fi franchises and Saturday-morning cartoons, history has no shortage of intelligent machines, real or imagined.

Humans have a curious habit of talking to inanimate objects. As children, we talk to stuffed animals and other toys. (Sometimes, we answer for them.) This carries into adulthood; we talk to plants, cars, televisions, kitchen appliances, computers, rocks... Sometimes we chastise them when they misbehave.
