This is amazing research. What I want to know is if they repeated the same experiment but trained the agents without language or, rather, on random data instead of language, would their gibbering eventually evolve into a structured language? After how many iterations?
In humans this happens. Isolated clans of non-socialized children (like the result of some disaster, or in a very neglected orphanage) have demonstrated spontaneous generation of novel language for collaboration amongst themselves.
