I think generally, games should move to using the GPU less for graphics and more for computation. Not just AI computation - those fancy GPUs are a big resource that simulation games could be taking advantage of and just... aren't.

(Yes, this is a Paradox callout. Give me less fancy particle effects in Vic3 and use the GPU for computing pop updates faster!)

(Probably the biggest barrier to this is the lack of a convenient C++/C#-level cross-manufacturer compute API. Vulkan is a bit too low-level for game devs to work with, OpenCL kind of sucks, and CUDA is NVIDIA-only.)
