More symmetry will happen when the home user does more things that care about symmetry. It's a simple allocation of spectrum (whether wireless, DSL or cable). MHz for upload are taken out of MHz for download.
It's more complicated than that. On cable systems, all of the upstream traffic has to contend for the available space, sort of like classic Ethernet. The faster you try to go, the more you lose to contention. With ADSL, there's only so much bandwidth per pair, and I doubt many users would want less download speed. There's also little reason to expect that many home users want symmetrical access. We weenies are atypical. Your normal broadband user watches video (which would better be sent as actual video over the cable, but that's a separate argument) and futzes with Facebook or Snapchat or the groovy app du jour. It's all mostly downstream traffic. R's, John
