The fallout of image generation will be even more incredible imo. Even if models do become even more capable, training off of post-'21 data will become increasingly polluted and difficult to distinguish as models improve their output, which inevitably leads to model collapse. At least until we have a standardized way of flagging generated images opposed to real ones, but I don't really like that future.
Just on a tangent, openai claiming video models will help "AGI" understand the world around it is laughable to me. 3blue1brown released a very informative video on how text transformers work, and in principal all "AI" is at the moment is very clever statistics and lots of matrix multiplication. How our minds process and retain information is by far more complicated, as we don't fully understand ourselves yet and we are a grand leap away from ever emulating a true mind.
All that to say is I can't wait for people to realize: oh hey that is just to try to replace talent in film production coming from silicon valley
