Humans have a tendency to see patterns where there aren't any. It goes back to our hunter-gatherer days. If you think a sound might be something rustling in the woods, it's better to assume it's real than to be eaten by a tiger.
There's a similar phenomenon in anthropomorphism. People assign personalities to almost anything. An owner of a Roomba will probably be willing to tell you about how their Roomba feels, and how it's "special". Most Roombas have a name, like you would give to a pet or a human.
When people hear about this tendency to assign personalities to things that have none, they smugly smile to themselves, sure that, "I'm not that silly." I look at it the other way. If humans are known to create imaginary personalities, then the most reasonable assumption is that people and animals don't actually have a personality, and we are merely projecting this facade onto what is essentially a robot made of meat.
