The plain fact is, ChatGPT is demonstrating a major step forward towards artificial general intelligence. It can't perfectly explain jokes, especially puns, but it's pretty darned close.
What happens next is what always happens next with AI. When it can identify and explain something, someone puts it in reverse and asks it to make jokes instead. HumourDiffusion v0.1, coming next week, and it will make you laugh more than half the comedians on TV. Version 7 will write sitcoms that are actually funny. Version 21 will win a Pulitzer.
Perhaps ChatGPT is what Peter Watts predicted in "Blindsight"[1] - intelligence without consciousness.
