I'm not concerned with dumbing down the desktop -- not a whole lot has changed in 15 years really. Big Sur really changed precisely nothing about how I use the computer. Certainly it's still highly functional and mostly gets out of the way. I'd be more concerned with locking down like iOS -- but that too, Apple has been measured and slow.

Although, I'm pretty disturbed by the locked-down trend. Kernel extensions are pretty much dead. It does feel like a matter of time until it becomes as locked-down as iOS.
