The killer app for the VR platform is eye contact.
In my opinion Zoom should be investing heavily in this, and Zoom’s market is the one newcomers stand to gain.
The giant feature that Real Life™ has and teleconferencing lacks is the subtle baton passing, engagement reading, and tone modulation that is enabled by eye contact. A square of video just isn’t the same.
My corollary hypothesis for why this hasn’t been done yet is that the Mark Zuckerbergs and John Carmacks of the world are on the autism spectrum, they get by without this information, and therefore don’t realize how much the rest of us rely on it.
