Same argument as for graphical user interfaces. Match the technology
to our human capabilities, and you "increase the bandwidth" between
the two. You either get a given task done quicker, or else get more
tasks done in a given time. Productivity means dollars. (Assuming the
ergonomics have been taken care of.) When the productivity dollars
exceed the total outlay, get into VR.

Simply run time backwards, and offer to remove your clients' mice,
then their graphical displays, then the CRT altogether, and then
their keyboard. Even threaten to remove their punch-card reader
and line printer, forcing them to interface by means of switches.
Switches are equivalent to combinations of wires, so remove them
too. Offer them Turing's proof that all computers are equivalent
to punch-tape machines. The only thing you lose is bandwidth. If
we all lived forever, wasting time wouldn't matter.
