This is only tangentially related but one thing I would like to see is the deep learning Starcraft bots to play 2v2 games and be required to send messages to each other (perhaps also preventing them from sharing LOS on each other’s units).
Like, just force them to send a message every 5 seconds, and see if it can learn to convey useful information about the state of the game, and then see if it can act on the information received.
I'll also feature it in Weekly Robotics (https://weeklyrobotics.com/)!
