There will be more programmatically generated content. No Man's Sky is a good example of a game that's almost entirely driven by AI. It's the only real choice for games that big (it'd be impossible for humans to design millions of unique planets with all the creatures, etc.). The upcoming Starfield may very well be one of the last games of this scale that uses individually created environments.
