This is a beautifully executed idea and if the demos live up to expectation the hype may even be warranted. But on a much more fundamental level (i.e. fancy 3D imaging and spatial audio aside), this also possibly suggests people would benefit from dedicated videoconferencing hardware. TVs and telephones do one thing really well (or at least historically they did), which is why even my legally blind grandpa could call his friends or watch^W listen to the news. There's a market for having a plug-and-play videophone now that we have the software to go inside it.
What are Zoom, Facebook or Apple waiting for?
