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.
