I wish more attention was paid to upload speed and latency to the rest of the internet too. People are backing up more personal videos than ever (including cloud connected security cameras, etc.). Latency is also very important to lower actual transfer times (since it will allow TCP to take full advantage of the bandwidth available). Latency also will be helpful for new experiences like Stadia and Geforce Now.

The latency is not a problem as long as you avoid packet losses. If you have losses then you pay dearly if there's latency. The latency itself doesn't present a problem, the TCP window size increases and takes care of that. The problem is packet losses, because (even with 'intelligent' retransmission) there's a lot of (the buffered) window to retransmit and then the performance dies. When the packet losses stay low, say, 0.001%, the latency is not an issue. (At work I did months of testing on TCP performance for a 900ms rtt high-speed link) But yes, upload speed is more important than ever. For my work-from-home setup I need to transfer lots of data both ways. And for my "cloud" backup etc. I need to push large amounts of data out of the house. And with fiber I get that, fortunately.
