It's complicated. Essentially, YT spends 24 hours a day trying to dodge the fallout of stupid decisions taken during the previous 24 hours, ad infinitum. They were bashed for certain decisions related to 4k video (which used to be called 4k, then changed to 2160p, then back to 4k, then back to 2160p), leading to the current name scheme.
4k and high bitrate 1080p are actually the same thing.
For starters, cull the immense amount of duplicated content. Look for some random common word and sort by recent, you'll see thousands of channels from India, Pakistan and similar nations reposting the exact same videos. There's also an ungodly amount of spam. These two things alone would, I'd guess, cut down a good chunk of server costs. Another thing is optimizing bitrate, I often get served "1080p" content featuring little more than a static image while browsing in my 6" phone.
Bushido is Japanese, this joke doesn't work.
Because it’s not like a wave, such as waves in the sea.
Actually, it is. It's the same meaning we've had for waves in physics since the first time someone figured how to plot a 2d graph. Only the medium is a quantum field instead of water, its amplitude is probabilistic instead of height, and instead of time we have some other property of distributions, usually space-time.
It’s a scientific fact that physical matter does not exist in its physical form when unobserved.
No, it's not. The quantum field and the quantum wave exist whether or not you observe it, only the particle behavior changes based on interaction. Note how I specifically used the word "interaction", not "observation", because that's what a quantum physicist means when they say the wave-particle duality depends on the observer. They mean that a wave function collapses once it interacts definitely, not only when a person looks at it.
It certainly invalidates physical reality as the “source of truth”, so to say
How so, when the interpretation you're citing is specifically dependant on the mechanics of quantum field fluctuation? How can physical reality not exist when it is physical reality that gives you the means to (badly) justify your hypothesis?
That's based on a pseudoscientific interpretation of quantum physics not related to actual physics.
