Your comment is phrased as though you think you're correcting me, but your point seems to be agreeing with what I said. My point is not at all about the technological ability of a computer to simultaneously process audio input and output.
The "limitation" arises because Teams/Zoom/etc all have mechanisms to prevent audio feedback. Participant A, using their laptop's microphone and speakers, will cause unpleasant audio cutouts for every other participant whenever they talk, even if Participants B-Z are all wearing headphones that prevent their microphone from picking up their audio output.
