That's exactly what I mean, all of those methods take some human effort, there is a human involved in the process. Now we face a reality that it might take no human effort to do... well, anything. Which is terrifying to me.
I do believe that humans are restless, and even when there is no longer any point to create, and it is far easier to dictate, we still will, just because we are too driven not to.
you know that there is still offline artforms like concerts theaters opera installations etc so i wouldn see it that negative. and we have nearly 100years of music and film we can enjoy. so maybe video is a dying artform for human to act in but there is so much more.
Now, we have entire TV shows shot on green screen in virtual sets. Replacing all the actors is just the next logical step.
