A very dismissive and short-sighted comment. The ambition here seems to go beyond the current implementation, to have a "magic" chat view that tracks voices and transcribes them in differing colors automatically and with minimal setup. I laud the effort and encourage the team to play this out for the sake of the hearing impaired. I hope that in the next decade deaf people--and their interlocutors--won't have to hobble together a slew of disparate technologies just to enable a group conversation.
