Yep, you could hack in some DWDM and scale with the capabilities of those endpoints, but at the end of the day it's still running over a shared medium. I don't think it's all impending doom and gloom, just a design decision that I think will not age well. It will be done eventually though I think.

Everything is eventually a shared medium. You don't have your own fiber all the way to Facebook. So the question is just at which point do you share and that should be a decision made on throughput and cost.
Yeah, as long as your ISP link isn't the bottleneck then it doesn't really matter if they are not as fast as they could be. I'm running on the cheapest FIOS plan and I can count on one hand the number of services where it is the bottleneck. In fact I can only thing of one at the moment: Steam, and even then only sometimes. Even then the difference is downloading a game in 12 minutes instead of 10 minutes assuming it isn't release week on a big game and the servers are slow.
