Mid-Atlantic In Motion 4K UHD

I find it amazing that most television is still only broadcasted in 720HD while 4K UHD (3840 pixels × 2160 lines) is getting in the the groove of entering homes.  4K TV's and computer monitors are still very expensive.  More and More cameras are offering 4K shooting these days.  YouTube offers it's users to upload a video in 4K format even though I dislike YouTube.  So are we going to fast or are some of us making horrible excuses why we shouldn't move to 4K?  Here's my timelapse film "Mid-Atlantic in Motion" in 4k UHD.  My Macbook Pro is approaching 5 years old so playing it at full resolution or "original" on the youtube player wasn't happening very well.
