Why humor is the frontier of artificial intelligence

This week my audience greatly appreciated the Motherboard post "Joke-Telling Robots Are the Final Frontier of Artificial Intelligence", so I decided to spend a few words on humor and artificial intelligence. Why allowing an artificial intelligence to joke is important? I like the honest way Bloomberg asks for the same question in a post which is now 4 years old, but is still a good read: Can a computer be taught to be funny? It doesn't seem nearly as important an endeavor as getting computers to identify malignant tumors or prevent airplanes from crashing, but being able to model humor is a key problem in attempting to model human thought. As Motherboard explains "Some specialists even see humor as the final frontier for artificial intelligence, because it requires mastery of sophisticated functions like self-awareness, empathy, spontaneity, and linguistic subtlety."
