It's genuinely a very similar problem. The max round trip latency before polite humans start having trouble talking over each other has been well studied since the origins of the Bell Telephone system. IIRC we really like it to be under about 300ms.

AI has processing delay even if run locally. In telephony the delays are more speed-of-light dictated. But the impact on human interactive conversation is the same.
