NEVER FORGET Wirth's Law:
https://en.wikipedia.org/wiki/Wirth's_law
> Wirth's law is an adage on computer performance which states that software is getting slower more rapidly than hardware is becoming faster.
My main suspicion is that OS have some kind of agreement with hardware vendors under the excuse of "it's new innovation which requires more CPU power". It's a hand in hand system where you need new software for the new hardware AND VICE VERSA.
It is veeeery hard to prove it, but it's similar to house appliances using designs and parts that wear out easily. Capitalism and growth DICTATES that it must sell, so it's impossible for a company to survive if it produces durable stuff. It's economically impossible to compete.
It's how the whole industry works (part manufacturing, etc), so it's not possible for a company to go against it. Capitalism cannot allow it.
