Hm. Nowadays a lot of games look alike. They use some 3D-Engine and most of the work is in the 3D-modelling and writing some interesting scripts.
For modelling and scripting I think we're not far away. A lot of games just reused old historical stories or fiction and a lot of stories feel like cheap soap operas. As soon as an AI can separate the good from the bad scrips it'll be mostly done.
You overvalue the HN crowd (or undervalue the AI hype-machine) considering you're downvoted and GP is upvoted (Another gamedev here smiling at GP's comment).
someday we will have models that can resolve physics to such degree to predict the future with surgical accuracy and when someone says "maybe models will become advanced enough to create a whole other universe from scratch" you will be there saying "highly doubt it"
