I really don't know how to reply to this.
Five years ago, there was nothing in existence that could respond well to a prompt like "Write a short story about my six-year-old daughter Emily traveling undersea to rescue her favorite sea horse, who's been kidnapped by the Shrimp King. Make her have several adventures along the way, engaging in side quests and making friends who ultimately help her succeed in her quest"
Today ChatGPT responds to the above with no difficulty, and part of the reason is that it has been trained not just to output reasonable responses, but aesthetically pleasing ones.
There is every reason to believe that video output will be more responsive five years from now than text is right now. Sure, it's possible it will be a little stilted, or a little generic, but it's possible it won't be.
Obviously we're both speculating, but I find it hard to believe that one minute today won't turn into hour-length in five years.
