Humans are smart. This makes us special, but not that special. White rats have a higher brain to body weight ratio than people do. As for intelligence in other animals? They might be smarter than you think.
Because the industry charged artists for everything, that put the artists on the line as "owners" of the work and its production, which means that now when they're looking to terminate old licensing agreements.
The mechanistic approach that the law takes toward the creation, production, and incentivization of intellectual property has more in common, in many ways, with the rules that govern a machine’s operation - “real” human thought and behavior is a lot more erratic.
