Watching these made me think, I'm going to want to go to the theatre a lot more in the future and see fellow humans in plays, lectures and concerts. Such achievements in technology must lead to cultural change. Look at how popular vinyl has become, why not theatre again.
I actually suspect one of the new most popular mediums will be actors on a theatre stage doing live performances to a live AI CGI video being rendered behind them - similar to musicians in a live orchestra. It would bring together the nostalgia and wonder of human acting and performance art, while still smoothing and enhancing their live performance into the quality levels and wonder we've come to expect from movie theatre experiences. This will be technologically doable soon.
