Train them to predict each other. Human brains being the most general-purpose objects in existence, this should be a very richly general training channel, and incentivizes brain-to-brain (B2B) interaction.
You may wish to consider a review of the political science machine learning literature here; prior work in that area demonstrates that only a GAN approach allows brains to predict each other effectively (although I believe that there’s some disagreement from Limerence Studies scholars).
