I'd argue that this failed though because UX really just means "design for maximum engagement".

Which means "keep the time between them using the UX and opening their wallet to a minimum" because that's the only place businesses care.

No one is building a delightful UX for running IR spectrometers.

And yet, at least in my personal experience, it is only since i started hearing the term UX that i felt UIs started going downhill :-P
