It's very interesting and indeed a huge progress, but arguably the most difficult part of story telling is hiring actors.

Maybe it isn't for big studios, but it is for a myriad of small studios. So real progress is when you don't have to hire an actor. When you can use voice generators, and sequential video generation - that's where the real shock is.

Because as soon as this happens to be available to single storytellers without any stuff, even at relatively low quality - it will transform the whole industry.
