I've read the article couple of times, to make sure I didn't missed anything, or if there was some line I missed. That's load of bullcrap! They're looking at the effects and completely mistaking them for the cause.
First, Thundrbolt 3 has absolutely NOTHING to do with networking. Number of devices supporting it is minuscule, and while they have 'wow' factor for using really extreme interface, they are far from common.
Second, high speed WiFi is the main factor pushing for 10GbE at home environment. What's the point of 1.7 Gb/s+ connection, when all you can do is mere 1 Gb/s, because cables? Add a NAS, and here you go, big damn bottleneck, you'd all be the same while using 802.11n. MIMO? What for?
Third, normal home users would love to have 10 GbE, if there was absolute lack of switches. Give us affordable 8 or 12 port 10 GbE switches. Consider routers presenting 6x 10GbE LAN ports (vendors that put 4 RJ45s on routers are the root of all evil!). You want to see good penetration and have cheap solution? USE IT! Soon, EOLed and deprecated enterprise equipment supporting 10G will start popping on auction sites, and it's selling like hot cakes - It's the same when 1G saw big adoption spike. But times have changed, and it's not ideal solution for many. Again, want sales - give us something we can buy!
Next thing is, quit yapping, that there is lack of content that would benefit from 10 GbE at home. Now, mostly true. See 10% market share, and grab popcorn and watch what happens.
There is considerable number of people, who still sport 100 Mb/s networks at home, because when they were lying down the infrastructure, 1G was prohibitively expensive. Their lousy low quality Cat 5 cables won't support 10GbE, and not even 2.5 or 5G. But... it's around the time, when they are renovating their homes - there is great sales potential there.
Next thing, going completely wireless is really the last thing we want. Forget about security (or lack of it) for a moment, but in most places where more than 2-3 famililes live close enough, 2.4 GHz is completely cramped, and 5GHz is starting to see congestion problems. Then, secure, stable and fast wireless is NOT plug and play.
Finally - we don't want half-baked and half-assed solution like 2.5 and 5G. It's a waste of effort, and looking for a niche that doesn't exist. This technology is already outdated!
