What has happened is that the computer has changed, it is no longer the big old tower but mobile phones, tablets and laptops. And the laptop and tablet space is already merging as laptops that has a touch display or a tablet with a keyboard.
Where the tower could be upgraded part by part including the operating system, the new type of computer doesn’t. The consumer usually buys a new one within a few years. This is where Windows 11 fits in.
I wouldn’t be surprised if you rent your computer in the future, you already have phones, which is a computer, with carrier subscription. This will of course also reduce user control even more. Combined that with the cloud computing and your computer is more of a client on a corporate controlled network.
The PC, Personal Computer, is dead.
