You will not be editing raw 8K video using the tiny 8 core CPU and 256GB storage space of the base model which the parent was referring to ($6000). Its true that for Hollywood projects, the price of this might not be a huge deal, even with the baller fully speced out model. Heck in my own industry (pharma) we're paying thousands and thousands of dollars for software that doesn't do much except have the magical 21CFR compliant sticker that regulators look for.
I wouldn’t put much emphasis on the storage. Most places that are doing video editing at this level are using all flash based SAN networking over 10/100GB Ethernet/fibre.
As for the CPU, I agree. However I’m not 100% sure on how much can be offloaded to the GPU these days, 5-ish years ago when I was working with video editors a lot, it wasn’t much that could be offloaded.
