What do people do on their phones ? I'm forcing mine in 3g all the time and it's faster than I need already. Why would you need 1ms ping and 1gbs d/u speeds ?
This sounds like phones having 4k+ screens to me, updating specs for the sake of updating specs, there is no real world need behind it. I guess many people are making big bucks in the scheme though, that's probably the major 5g benefit.
Remote desktop, ssh, VoIP, gaming... anything that's interactive. All of those work better and are more fun to use with low latency.
Even plain web browsing can be much more enjoyable with a low latency connection assuming there's no other bottleneck.
Our computers are millions of times more powerful than back in the days but somehow my 2018 macbook pro crawls to a halt if slack displays more than 2 gifs at the same time.
Anyway, I think we're artificially creating needs that aren't needs in the first place. "b-bu-but how am I supposed to telework from the subway if I don't have my 5g =(", "I can't even stream youtube 8k videos from the bus =("
