This video perhaps best explains what I have been trying to say all along. Specifically at T=3 min.
Apple is slow to update their desktops because that's the furthest from what they feel a computer ought to be.
The same design-led process which let to Apple creating the iPhone, iPad, Apple Watch, AirPods and (currently working on) AR glasses. Even the much-maligned Apple Watch band is an example of Apple "getting it". While it doesn't improve the functionality of your apple watch, it helps improve the aesthetics, which in turn leads to more people being willing to buy one.
When you focus only on technology in a vacuum, you get smartphones with hardware keyboards, netbooks, circular smartwatches and folding phones.
The reason why Apple hasn't done any of the above, and are instead focusing on creating what they are, is design.
Apple Glasses vs foldable phones is the latest example of Apple's design culture leading to an entirely different product than what engineering-led companies are doing.
If you don't like or want the vision of technology that Apple is promising, then the best option is probably to get out of the Apple ecosystem now. Apple is never going to stop being Apple, and that means not listening to their customers and continuing to give them what Apple thinks they want, rather than they say they want.
For better and for worse.
