This is all just happening on the coattails of AI's popularity right? Hasn't the technology to do this, and whatever similar stuff people are complaining about, been available for years? Were all the agents in whatever matrix movie individual actors? Didn't Justin Timberlake perform with dead Micheal Jackson a decade ago? People are just milking AI hype. Or is there really some material step change that's happened?
