To be fair, we're getting diminishing returns every iteration. 7 is only 1/6th more than the last one. And 8 will be just 1/7th. I don't blame people for being a little fatigued by this.
They don't specify how near zero "near-zero" is, but I use an Oculus Quest 2 and VR Desktop and the latency is 4-8ms, which is 0.5-1 frame at 120fps. I know Air Link is bad, but that seems more down to their software than anything else so a higher tech router isn't going to do much
Sure, it’s already good enough for everything I use it for. However, I hope and expect to be doing cool new shit with way better wifi in 20 years. So, in the chicken and egg problem of technical capability vs cool applications, I am fine with increasing specs way in advance of killer apps.
No. It's not good enough yet. I'd like to have wifi that doesn't instantly drop speeds if I'm not less than 2ft away from the router. Still waiting on that technology. Wifi will never be "good enough" until it's as good as ethernet.
That's probably fixed by getting a better quality router or adding access points if the issue is the building blocking signals. That's not a problem with the standard, and the new standards are for even higher speeds which actually have lower range at those bandwidths.
