We have an interesting problem. We don’t want fake news or fake people telling us fake things in our ‘real’ world. Yet we want believable people who don’t exist to live in our games and virtual worlds. We want digital bots and assistants that can emulate personess to make it easier to work with them. The tools to make both are the same. https://thispersondoesnotexist.com/ is a site created to demonstrate the technology and give people an understanding of where things are going.
Something happened to game engines, they became tools for world building all by themselves. They are used by movies and tv productions now. This idea of all this processing power and real-time combines with films need for tools that let them build quick. We might just get the VR tools all of us are waiting for?
