I am top posting my response to the below, because I find Paul's
statement wll articulated. I don't want to break the flow, but I do have
a commnt or two.

I, for one, would not deny that vision, or the gui/mouse UI provide
advantages not easily replicated through other senses and modalities.
However, it is also most true that all of us, each and every one, have
disability ahead of us in our lives if we live long enough. I am
thankful that J.S. Bach simply dictated Art of the Fugue would he could
no longer see to write it himself. Similarly, I know we are all thankful
that Beethoven kept writing it down when he could no longer hear it
himself.

The point of accessibility is more than just providing something to do
for persons with disabilities, however. It's about exploring and
refining human abilities--those abilities we all share (mostly). When
one fasts one gains an enhanced and refined taste--at least for
sometime. When one experiences Eric Satie's Vexations (as I did at my
college in the 1960's), one might find one's hearing amazingly enhanced
and refined for nuance.

In the case of user interfaces, exploring adapted presentation and input
modalities similarly enhances and refines our options with computers.
One needn't use a wheelchair to appreciate the curb ramp at the street
corner. Good disability design is really human potential
facilitation--and always will be. Making something work for someone who
is blind is never about vision, it's always about the remaining senses
that the person shares with other human beings.
