People cant see 4k resolution from normal sofa viewing distances. Why do we need 8k televisions? Besides the tv industry needing a new resolution to sell more TVs?

I doubt I could tell the difference between 4k and 8k though.
I suppose doing the math, I would expect to be able to tell the difference between 4k and 8k on a 110" TV.
