The Truth about 8k

What's the deal with 8k? Can anyone really tell the difference? How much does it cost to switch to 8k once you factor in computing, storage, and a camera and lens upgrade? When is 8k useful and when will it make zero difference? Tony & I set up a blind poll to see if our viewers could see the difference between 8k, 4k, and HD. We discuss the results and if we think 8k is worth the switch.
