Are you trying to sell us PPI as something new here?
We haven't reached the point yet where mainstream gaming devices are able to reach proper PPI, so demanding more and more resolution is just fine.
Also, it's never a great idea to fix human senses to hard digital numbers. The brain and our sensory organs do a lot more than just process sensory information directly. They always take all of the senses into account and do a lot of post processing. That's why a 2000ppi image will still look better than a 1000ppi image. If it starts moving, the contrast will be even stronger.
Next you have to consider that our brain and organs are trained more and more for higher perception and standards. So even if we can't process the difference between an 8k or a 16k picture right now, we probably will be as soon as we're used to 8k footage.
So until we reach a point where our brains really cannot tell the difference anymore we will still ask for more and more and that's ok.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
