It's an interesting proposition. A highly abstracted, very high level, very modal multi-user system where users actually interact instead of being sandboxed.
Keep in mind that "anti-X" stuff tends to resemble the original "X", thus despite the antagonistic name, this is probably not as revolutionary as we will get.
What would be the Mac design principle way of doing this then? Would every command line tool then be an Anti-Mac user interface?
"Anti-Mac interface" doesn't seem to be pejorative in this context.
More or less helping move from 'direct manipulation' to delegation. It's not so much that this is moving away from any particular Mac principle so much as towards the sort of system outlined in that essay.
