No, quite the contrary. Unix is about
not having the "everything is one big monolithic blurb" complexity.
And for the people who want a UX that's designed the way described in the Jobs quote, there's several Desktop Environments doing exactly that. The issues with them not being more attractive for I-dont-care-which-OS-I-just-want-to-use-my-computer people are:
- Lack of polish due to lack of manpower (due to the existence of several competing DEs and everything being volunteer efforts). This is of course slowly getting better over time.
- Unfamiliarity, and lack of helpful neighbors. That's something that could quickly reach a tipping point where enough helpful neighbors are around to enable people to switch, which will again increase the amount of (possibly helpful) neighbors. That's why people have predicting the Year Of The Linux Desktop Any Day Now for decades.
- That one irreplaceable program that doesn't run on Linux. I'd say that's almost solved nowadays due to the attention Wine is getting, and the ease of putting just that one program in a VM running its preferred OS.
Note there's no bullet point involving complexity, or love of arguing.

presents as a terminal multiplexer.)
