The thing is that the pandemic has changed the game on the ground: there is an actual feature differentiator to be had. But having dealt with the Linksys folks in the past I don't put out much hope that they'll take advantage of it. The software development side was a vast black hole where time stands still. It seems the entire industry is like that.

Michael,

Even 100 Mbps Internet is fine for Zoom, as long as the uplink speed is at least 10 Mbps. The average zoom session requires 2 Mbps up and down, and even for the lavish six-screen executive sessions, 6 Mbps is plenty good. So arguing that 10 GbE is necessary because “pandemic has changed the game on the ground” is silly.

So, sorry, 10 GbE is a hobbyists fantasy, not a marketable product. If hobbyists want 10GbE, let them pay for it like the rest of us, and let them play CoD from inside  freezing data center :)

I'm not saying anything about 10G, other than my initial query as to whether any residence could possibly need that much bandwidth. But buffer bloat is a problem with a lot of us still stuck on DSL with no prospect of anything better. It's not the bandwidth per se, it is how the bandwidth is consumed at home. Better queuing disciplines than tail drop with a gigantic queue could help zoom meetings a lot where bandwidth is more constrained. And regardless of bandwidth, huge queues are not good for real time traffic for anything. You'd think that gamers would be acutely aware of this and create a market for routers that cater to their hunger for less latency.
