Re: Chicken, Egg
Eh, I'm skeptical there is any need for gigabit speeds to a single client, let alone multi-gigabit speeds. What's the use case? Faster downloads of the latest iOS update? If you are working with huge video or CAD files and have a very fast fileserver, sure, but that's a corner case and one that's usually handled by using a wire.
We've reached the limit of sensory input to humans, even streaming 4K Blu Ray quality video is only 100 Mbps or so. Anyone who thinks we're going to keep going to 8K, 16K and beyond just because it will become possible needs to read up on diminishing returns, and understand why consumers didn't care about better-than-CD quality audio formats and instead were perfectly happy with less quality in the form of MP3 and AAC.
Not saying we'll never need gigabit speeds to a single client, just that there isn't anything that needs a gigabit today or on the horizon, aside from a few niche cases that don't justify the development cost. Luckily 802.11ax is about using spectrum more efficiently to allow more clients to transmit simultaneously, rather than being about letting one client use more of it at once like previous standards.
