The analogy I like to use is from the fictional universe of Mass Effect, which distinguished between VI (Virtual Intelligence), which is a conversational interface over some database or information service (often with a holographic avatar of a human, asari, or other sentient being); and AI, which is sentient and smart enough to be considered a person in its own right. We've just barely begun to construct VIs, and they're not particularly good or reliable ones.

One thing I like about the Mass Effect universe is the depiction of the geth, which qualify as AI. Each geth unit is not run by a singular intelligent program, but rather a collection of thousands of daemons, each of which makes some small component of the robot's decisions on its own, but together they add up to a collective consciousness. When you look at how actual modern robotics platforms (such as ROS) are designed, with many processes responsible for sensors and actuators communicating across a common bus, you can see the geth as sort of an extrapolation of that idea.
