> The 20Mbit the EFF is complaining about is already good enough for one 4K video stream. Still, only one, and only if that 20Mbit is an actually achievable transfer rate rather than a theoretical cap. 100Mbit would be much more comfortable, especially for multi-user households.

Focusing explicitly on "20Mbit ... is already good enough for oen 4K video stream", this is only true if the peak rate is 20Mbit, or if it's not a real time application, where buffering can be applied to smooth out that stream.

Try streaming a 4K RDP session on 20Mbit, and watch that experience degrade rapidly during any periods of high motion on the remote machine.

Averages only work for workloads that can be smoothed. For any real time applications, what matters most is the peak rate. For example, a single 4K RDP session can peak at over 80Mbit. Even at 50Mbit, the session will become unusable during peak motion periods, in the worst possible way: you lose the content, and there's a delay before you're able to interact with the session in real time again.

So yes, 20Mbit is good enough for lowest common denominator stuff, but there's a lot of value being ignored outside of watching TV.
