Wow, this is a pretty ableist take. Deaf people or hard of hearing exist.
I've got a hearing problem where I struggle to make out what people are saying on a phone but with a video call I can add lip-reading and visual cues which helps me keep on thread.
Which is excellent, and I totally support that. But that doesn't change the market dynamics that I'm describing. We probably should live in a world where what drove the adoption of video calling was supporting the hard of hearing. But we don't, so it's not a relevant factor for the market analysis of what will drive the adoption of 3D video.
