Our infrastructure at times goes back 200 years old. We have rules and words in today's networking linguo that go back 70 years old. You can't just go and tell that it would have been better this way. It absolutely would. And I'm happy for Swiss people who can have 25gpbs at a fraction of the cost. But you can't do that with an emerging tech that is trying to replace existing architecture.
Swiss guys built all that after the tech was wide-spread in the world, and they have built it over a very outdated infrastructure. It was a breeze.
US just unable to use this approach. We can't.
Should we come up with a new one? Yes. Should we look at the Swiss solution and try to replicate it. Yes. Is it awesome? Yes. Would it work here? No.
