I think the main reason Dune is faster compared to Jenga is that it's using a more efficient incremental computation library under the hood. It's difficult to explain the details in a comment but I hope to write this up in a more technical blog post or article someday!

A Revolution in How Robots Learn A future generation of robots will not be programmed to complete specific tasks. Instead, they will use A.I. to teach themselves.
