I can't help but feel this is missing the point. Ideally, next refresh click latency is a fantastic goal, we're just not even close to that.

For me, on the web today, the click feedback for a large website like YouTube is 2 seconds for first change and 4 seconds for content display. 4000 milliseconds. I'm not even on some bad connection in Africa. This is a gigebit connection with 12ms of latency according to fast.com.

If you can bring that down to even 200ms, that'll feel comparatively instantaneous for me. When the whole internet feel like that, we can talk about taking it to 16ms
