Sprint to Launch 5G Network Next Year

I've always been excited for what phones will be capable of in the coming 5-10 years. Sprint seems to be gearing up for a big 5G launch, however.. it looks like it'll be useless?

Sprint Corp. said it planned to launch a commercial fifth-generation, or 5G, network in early 2019, putting it roughly in line with its rivals’ rollout plans as it charts a new course following the collapse of merger talks late last year with T-Mobile US Inc.

It isn’t entirely clear how necessary 5G will be for smartphone users: most 4G connections are already fast enough to stream HD video and play online games. None of today’s smartphones would work on the technology.

Do you guys think there's a limit to how fast your phone can get? I pretty much have 4G LTE everywhere I go in the country at this point, and most of the time it's so fast that I get an instant load-up of whatever I'm clicking on. I can see upload/download times always increasing; but to what extent? Apparently, no phones at the moment would even be able to utilize 5G, but it could be used by more sophisticated mechanisms that maybe authorities/militaries/communication services use. It also seems like every carrier is preparing for 5G in 2019, so i'm sure in 2020 there will be many phones capable of 5G. What phone network do you guys rely on?
