"Bandwidth" isn't that difficult a concept. Netflix has the power to, essentially, cause the entire Internet to buffer.
House of Cards caused a massive hole in total internet bandwidth - Business Insider
We agree on one thing. The internet is not being managed by anyone more perfect than ourselves!
I could tell you tech stories from my day, before and into the rapid growth of the first decade of the internet. Stories about the best and brightest, engineering in single points of failure, creating bottle necks, and using the least effective equipment, made by companies with the most effective sales pitch, and hot female sales "associates."
And about bandwidth; just because my kid is in the middle of a massive growth spurt, eats like a horse, and often takes a dump like one, (or maybe even an elephant), doesn't mean I feel the need to go out and increase the size of my sewer plumbing. That is the essence of a "clogged bandwidth" argument.
The problems with this are as follows; technology is still increasing at a blistering rate. First example. Neighbors built a house across the street in 2001. He was a VP with the Glass Worker's Union. They moved "Fats" up from Shreveport, LA, to handle negotiations and oversee mothballing every fiber-optics facility in America. Why?
In the length of time it took investors to build factories to produce fiber-optic cable, sending and receiving technology increased so fast that 100k to 1M more transmissions could be made on the same fiber. Turns out, by the time these productions facilities hit high gear, we had a two hundred year supply of cable, due to rapid increases in technology. So where the "clogged" argument first fails is that internet traffic shares the same "constant mass/volume" feature as sewage. It does not. The smell test should be your first indicator that an analogy between the two may not be true.
Secondly, though the internet and components are designed by rocket scientists, the implementation, maintenance and etc., is not. We could talk about a hundred conversations that could yield empirical data that pieces of our networks are run by the lowest cost solution. And the cost of that sacrifice is the dynamism and robust nature that could be the internet. The savings is a couple of dollars more for people that own yachts and summer homes already.
The most interesting piece of this is the history of the generational improvements to what is called Transmission Control Protocol/Internet Protocol. It is a study of something that could have been opened to save gazillions of dollars and provide a faster, more robust internet, but has been throttled at every turn by the big-money decider's.
