this is kind of an unfair comparison. Whats the endpoint of generating AI videos? What can this do that is useful, contributes something to society, has artistic value, etc etc. We can make educational videos with a script but its also pretty easy for motivated parties to do that already, and its getting easier as cameras get better and smaller. I think asking "whats the point of this" is at least fair.
The end point is enabling people to put into video what is in their mind. Like a word processor for video. When you remove the need to have a room full of VFX artists to make a movie, then anyone can make a movie. Whether this is beneficial is dubious, but that's an end goal if you are looking for one.
