LOL, that will never happen. First off, a lot of new content is *only* available from streaming services, not on any cable channels at all. Second, while you might complain about content being scattered across multiple streaming services, I see it as giving consumers options. If you only want to spend a little money (say, somewhere between $5 and $15), you can just subscribe to a single paid service at a time and switch them out on a monthly basis since you're only committed for that long. Or, if you like, you can spend a lot of money and subscribe to lots, or even all, of the various streaming services. And using an aggregated UI, like the TV app on Apple TV, or the Google TV software on the new Chromecast, helps you search, browse, and keep track of content across lots of different services at once.
The main thing that's keeping cable TV afloat any more is the live sports content that is exclusive to it. That and simple inertia/familiarity. But with each passing year, cable TV will have fewer and fewer subscribers while subscription streaming services continue to grow.
