I saw a stream the other day that was just the output of an AI trained on a popular streamer’s past streams. It would select a random clip for video, respond to viewers’ comments in the voice of the streamer. It even superimposed roughly corresponding lip movements on the video.
I've listed to some popular podcasters. Over time, they all run out of material and their newer podcasts are just rehashes of the old ones. I suppose AI will take over that job!
