My fear is that this is going to lead to an optimal orchestration language. For example, that Claude switches to Sumerian for all communication between agents. One thing is if they try to silo like that, but my real fear is that it may actually perform well.
(Not sure if it would be Sumerian, Esperanto or something more artificial. As long as it is esoteric enough for one company to hoard all the expertise in it.)
I've seen Antigravity outputting chinese characters in its thinking traces from time-to-time.
I also remember chinese being discussed as a potential orchestrating language but I don't remember the sources, so 100% anecdotical.
