You don't think they can write or create images/music/video? If you are being seriously, you should try some of them out - they are incredibly capable now.
Yeah, they can technically create those three things. They are in no way up to par if you have a single bit of artistic taste.
Even the best ones really aren't very good at this yet.
I think their question is whether it's replaced work in industries focused on that - AI movies becoming popular and very profitable, AI written books selling large numbers etc
Very possibly on the way but so less uptake than software engineering for sure.
