It’s a chicken/egg problem. We need 8k so we can use bigger TV’s, but those bigger TV’s need 8k content to be usable.
What kind of TV do you need bro? A 60 inch with 4k is more than enough, especially when you think about how far you are gonna sit from a 60 inch TV. Only suckers buy into 8k. Same people who bought those rounded screen smartphones thinking it will be the new thing. Where are those phones now?
