>It's actually good enough that my parents have their morning tea together practically almost the same way they used to when they were physically together.
I don't understand why this sort of persistant 'portal' isn't more popular. But 10 inch screen is so small! A 55 inch TV is what, $300? Put it portrait mode and that's a life size portrait. The feeling of presence when the person's head is the correct size is so strong! I know Facebook sells something for the TV but can it be left on all day like that?
I want it feel like one half of living room is a shared space, at all times. Like the couch is split in half by a portal. Then it just cycles through a list of friends and family with the same setup to find someone else watching Netflix or whatever, and you can casually join them just like a real shared living space.
I don't need 8k or 3D tv. Just a 55 or 65 inch TV on the wall at the end of the couch!
