Re: 5G aims to cover a wider set of use cases from the outset.
"Its funny how many people in technology don't want to move forward & 5G is not moving forward for the sake of moving forward, it'll be a true game changer."
It's not a question of not wanting technology to move forward. Rather, it's the exact opposite - people complaining about 5G generally want technology to move forwards, but what we're getting instead is a meaningless wishlist full of buzzwords. Whatever ends up with the label 5G may well be a big deal, although it's unlikely to be any more game changing than 3G and the thing that ended up with the 4G label were; the latter being a good example of exactly what happens when you start with a vague wishlist instead of a clearly defined and achievable standard - we still don't have anything that meets the original 4G spec.
The problem is that 5G is currently a label waiting to be attached to something, but all too many people keep talking about it as if it's a finished standard that will be on consumers' hands within a year or two. It will apparently be low power, low latency, high bandwidth, distributed, femtocell, AI-driven, machine learning, blockchain, unicorn, rhubarb, rhubarb... but there's deathly silence whenever anyone asks what it actually is, how it works, and how it will be used. Because those questions all use the present tense, and presently it's just a list of things that would be nice to have with little to no idea how it will be actually achieved in practice. We'd love technology to move forwards, but that requires more than a game of buzzword bingo.
