There are people on the internet with about 2-3 ms of ping. I'm not a network engineer to tell you how that's even possible, but I've seen it. I'm on 15ms to most game servers right now on a copper line.

Google Stadia failed for different reasons. Nvidia Go (or whatever it's called) still exists. Just because I have a shitty copper line doesn't mean fibre will be as shitty.
