Meta (Facebook) quietly revealed their latest version of virtual reality tech as a demo between Mark Zuckerberg and podcaster Lex Fridman. The video of their interaction is worth watching to get a glimpse of how virtual presence might work between two people. Although each person is wearing goggles, they experience a full-sized 3D avatar of the other person without goggles. It’s a technological trick that seems to work, and might be in our future as something better than Zoom. — KK
