By that time, I hope the cable infrastructure goes the way of the telephone landline infrastructure, in that any cable provider can pipe their signal over a shared network. That would add competition and reduce prices.
How does that get accomplished though? The physical cable pipe is owned by the same people that like their cable TV revenues "as is". A government request for sharing it will be met with scoffs and long-term delays. A government mandate for sharing will be met with scoffs and long-term delays (court battles). Realistically though, there's a big reason why these same companies are major contributors to both political parties. It's how extraordinarily anti-consumer laws get passed like:

Or maybe you are imagining an all-wireless internet via LTE or similar? If so, there is not enough bandwidth for that to even get close to an option for the masses. And we already see how the masses are being conditioned to pay for relatively small amounts of wireless bandwidth. Imagine the clash when some kind of all-internet cable TV replacement solution clashes with small data tiers and tiered pricing.
IMO, the #1 problem with the cable TV replacement dream is the fact that any such replacement depends on being delivered to consumers through the very same pipes owned by those who like cable TV "as is". It's easy to dream about what's in it for us and Apple... but why would the cable company that is also our broadband company allow that to happen? through their own pipes?
The #2 problem is our belief that we can get some kind of al-a-carte, commercial-free replacement and cut our monthly bill by 80-90+% and still somehow keep all the shows that everyone likes being produced at the same quality level as now... and still persisting a motivation for entrepreneurs to take high risks on creating a good mix of new pilots every year too.
The #3 problem is the huge subsidy per household paid by the existing commercial-based model (including commercials running on the 190 channels "I" never watch) being killed off in al-a-carte world but believing neither we consumers nor Apple would have to make that up; if so, who's left to eat that huge loss in the Content Creator + Apple + Us chain?
#4 is #2 & #3 stated another way- the naive math concept which goes "I pay $100 for 200 channels now", "I only want about 10 channels", "$100/200 = 50 cents per channel", "My bill should be cut to $5 per month"... and believing that al-a-carte would actually work that way; in reality, an al-a-carte model would probably kill off a lot of "junk" channels "I" never watch (and with them would go the commercial subsidy revenues from commercials "I" never see either) yielding a much smaller mix of the very subjectively "good" channels "I" do want in my new package of just 10 channels. How much would those 10 channels cost? Probably at least $100/month plus whatever it would cost to make up for the lost subsidy revenue. Yes, $10+ per channel, not 50 cents.
And so on. This has all been discussed multiple times before and there's always a split. The dreamers will just pretend there are no real problems in the above... that Apple will find a way. The realists will recognize the many holes in that dream and add that for any cable TV replacement revolution, it's probably us consumers that are paying up MORE than we do now if there is any chance of it actually happening.
Otherwise, you need other kinds of innovations to solve key problems. For example, a new way to cheaply link us directly to iCloud and bypass the last mile in place now would solve #1. That's a big missing piece in putting real potential in the dream. What is that innovation? It's not LTE or similar. It needs to be something else with wired-like bandwidth probably without the wires (so that it can reach the world without having to build out a ton of new physical infrastructure).
OR, we consumers need to say/show we're willing to open our wallets much wider and tangibly demonstrate that everyone else in the chain will be able to make much more money than they make in the model "as is" (because that's the biggest driver of business change). If we average $100/month now, we probably need to show them we'll pay $200 or more per month for our fewer channels and/or less diversity of programming in this dream. As long as the other links in the chain can all make more money than they do now, we'll probably get what we want (except for the cheaper monthly bill part).
