Look. I'm a small startup employee. I have a teeny tiny perspective here. But frankly speaking the idea that Netflix could just take some off the shelf widget and stuff it in their network to solve a problem... It's an absurd statement for even me. And if there's anyone it should apply to it would be a little startup company that needs to focus on their core area.
Every off the shelf component on the market needs institutional knowledge to implement, operate, and maintain it. Even Apple's "it just works" mantra is pretty laughable in the cold light of day. Very rarely in my experience do you ever get to just benefit from someone else's hard work in production without having an idea how properly implement, operate, and maintain it.
And that's at my little tiny ant scale. To call the problem of streaming "solved" for Netflix... Given the guess of the context from the GP post?
I just don't think this perspective is realistic at all.
