Have already seen countless major ad spots using ai generated videos; big name companies. One major use case.

Much like the widespread availability of cameras has caused a massive increase in photos of things that would otherwise not have been photographed, I think widespread availability of AI video/image generation will cause a massive increase in media from everyone who wants to show their thoughts to others. Of course the vast majority will be uninteresting slop, because most people just aren't very creative or original, but there will definitely be more chances for those who are. The popularity of AI parody videos is a sure sign of things to come.
