> Humans can’t process multiple audio streams simultaneously.

I'm not sure this is true. I think our comprehension drops when we do, but we regularly process background noise and speech at the same time, same for people interjecting over others with simple things like 'excuse me' or similar.

I may be misunderstanding or stretching your point but it's interesting to think about.

I also immediately jumped to surveillance tech when I read it though I can think of other areas it would be useful. Home assistants like they mention in the article would be a great use case, not for multiple inputs at the same time, but to isolate the speaker addressing the home assistant.
