I don't feel the need to take advice from someone that thinks 4k is an "aspect ratio" (as quoted at 2m55s into the podcast). Hard drives are dirt cheap and any macbook pro post 2014 can handle 4k with little to no issue. The argument that 4k isn't worth it but 2k is? Come on? That's the same argument as saying 720p is just as good as 480p ten years ago... Not trying to troll, but a lot of this guys points hold little validity.
