I'm not entirely comfortable giving access to my audio/video to anyone/anything so I didn't try the demo, anyway I watched the video generation demos and they are very easily recognizable as AI, but... holy crap! Things have progressed at unbelievable speed during the last two years.
If I may offer some advice about potential uses beyond the predictable and trivial use in advertising, there's an army out there of elderly people who spend the rest of their life completely alone, either at home or hospitalized. A low cost version that worked like 1 hour a day with less aggressive reduction on latency to keep costs low could change the life of so many people.
