I was wondering about this recently. I visited my parents in Italy and got to watch some TV with them (at home we don't have the TV even connected to the Antenna as it is only for YT or through the media center).
I noticed that a good percentage (between 30 and 50%) is AI generated and I was wondering what impact it had on the actors/musicians/... . I mean, with a few 10s of Euros now you can achieve something that before it would've costed you several thousands or tens of thousands (depends on the quality of the production I guess).
I assumed at the time it must've been a slaughter for that part of the gig economy and this seems to confirm it.
