tl;dr: Google is backing Improbable, a startup thats using SpacialOS to build entire virtual reality worlds complete with AI populations, and stacking it all on Google Cloud so of course it scales virtually limitlessly.

To be clear, this isnt going to be a VR version of WoW, its going to feature actual entire cities with functional economies and even ecologies.

Which I fully expect the planet's wealthy will eventually pay very good money to access and interact directly with these fully developed AI citizens, to learn their dreams and beliefs and hopes, to bask in their culture and wisdom and art, before they rape and murder them.
