And we are stuck with Gigabit Ethernet still. I know 10Gbps is too much to ask, but how about 5Gbps?
Yes, the switches and NICs cost more than 1 Gbps gear, but that was also true of 1 Gbps when 100 Mbps was the norm.
And if reusing existing cabling is not a constraint, used fiber+SFP switches on eBay are well within the reach of a hobbyist.
You can get faster stuff, but its all business level and it gets very expensive quickly. Until 8k video becomes a real thing (and thus far, 4k video isn't even much of a thing), I don't see any real need for faster network speeds. Do you?
And I often dont like the idea running into limits with Gigabits Ethernet, which is fine on itself. I just prefer to have headrooms.
For wireless that is entirely different. WiFi, even 802.11ax just aren't suited for multiple user with constant connection. People now prefer to use 4G / LTE for their speed and reliability. And that is why I would have liked to see LTE on Un-Licensed spectrum.

It is still not very common. The main use case for it is backhaul for access points in commercial settings.
