I'm starting to feel like we've long passed CD levels in wireless standards
Yes, the title makes no sense at first glance, let me explain.
Anyone remember DVD-Audio? It offered better quality than CDs, but it never caught on. Why? Surely for a myriad of reasons, but one of particular importance was that "people didn't care". The difference between CD and DVD audio quality was inaudible to most.
I'm starting to get the same feeling with wireless standards, especially those pertaining mobile networks. 4G already covers most use cases for the average consumer, you can watch full HD videos while walking like a zombie on the street if you're so inclined, sites load in a second or less, etc. Unless we find something that people really want and requires a lot of bandwidth (and no, 8K video is not a good candidate, for the very same reason outlined above), this is starting to feel like technological advancement for its own sake. In other words, its return of investment seems questionable.
