Not when all of those devices have 100% dependency on the cable company's cord. In other words, if you literally cut the cord, all those devices become door stops. Cable will get theirs no matter what. We should quit deluding ourselves that all of us can "beat" the cable company when they are also the only broadband provider for most of us. They will get theirs either way.
I suspect cord cutting means we will eventually be paying net more for net less. In other words, save the $100/month for "200 channels I never watch" by being a trendy "cord cutter." When the masses move on this concept, Cable will want to make up for the revenue losses. Tiered pricing for "higher bandwidth users like video streamers" gets implemented. Now our $50-$80 broadband bill rises to $80-$120 for broadband only. Then we also subscribe to Netflix, Hulu and various individual apps for maybe $30-$50 more. Where our cable+broadband combo used to cost $60-$100, now our cord-cut "cable" plus broadband costs $130-$170 and we have access to much less programming... though conceptually, only the stuff we want to watch (until of course, some other stuff is running on apps or channels not in our subscription pool... then we just pay more for it or do without).
Step a little more forward in time and read threads full of people whining for some kind of "value package" where all programming is available in a single app for a relatively low price, perhaps with some kind of on-screen guide that simply shows everything available to watch right now and maybe some DVR-like functionality... just like the "good old days": "I remember when I could get 500 channels for about $70/month. I rarely watched many of them but they sometimes had something interesting on. Now I pay $150/month for what is equivalent to about 10 channels in the old system. I used to think al-a-carte would cost so much less but it's actually much more expensive. Those greedy cable companies stuck it to us again. The Government should do something about this. Apple should do something about this. etc."
