I want to see deepmind make a bot to play team based first person shooters like csgo and rainbow6 siege, to stack up five of them against a team of professional players.
Honestly that probably won't be too interesting as (a) one AI could perfectly control several agents (ie perfect coordination of global strategies) and (b) an AI has low to no reaction times and perfect aim (aimbots already have that) so I would expect that would quickly result in a slaughterfest.
What would be interesting would be 5 independent AIs (even just different instances of the same AI of course) using the same interface as human players, so the same controls and the same video output
I am pretty sure aimbots access the internals of the game rather than reading the video output to identify the silhouette of the enemy.
IIRC multi-agent domains are in their own category specifically because a single agent posing as "multiple agents" usually can't solve such environments, you need multiple agents with varying degrees of dependence
Same applies to dota2, and it was very interesting what they did there.
But yeah first they would need to simulate how human players react and aim, or it would be impossible to play against.
