It is. You can hire the people who have solved it to do it for you.
"GPGPU compute is a solved problem if you buy Nvidia hardware" type comment
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.
Right. They have to hire one of the companies that does this. Each of YouTube, Twitch (Amazon), Facebook and TikTok have, I believe, handled 10+ million streams. The last two don't compete with Netflix.
Offering it for sale != having solved it.
