Re: your robot example, my first reply would probably be a joke, or a sarcastic response because it's clearly a silly question. "Yes, humans should work for our robot overlords and couches are just a way of slacking off", "Nah, the garage would be a much better place to store a chopped up couch".

ChatGPT has the most boring, dull, and humourless personality in existence. Maybe it can be programmed to inject some sense of humour, but will it be able to determine when to use what humour, if at all? You wouldn't respond with a silly answer during a job interview. You can use some humour in job interviews, but you don't want to be a clown unless you're interviewing for the position of clown. Determining when and what humour is "appropriate" isn't simple (and humans get it wrong too sometimes).

Maybe that should be the real test: does ChatGPT have a sense of humour and does it know when to be serious?
