There was a joke bumper-sticker in the valley back in the day that said "Windows 95 == Macintosh 89". But the critique of this was "Macintosh 95 == Macintosh 89". In the same way, "NeXTStep 89 == MacOS X 2001 == MacOS X 2015 == MacOS X 2025" except that they hadn't steved everyone from the user experience research group in 2001 and there were vestiges of #a11y features left in Yosemite.
Complaining your current version of MacOS X has a worse user experience than it did 10 years ago is like buying a Tesla and then complaining about its resale value.
