“It is easy to imagine cell phones that will see for those who cannot
see, read for those who cannot read, listen for those who cannot
hear, translate for those who cannot understand, find those who are lost and remember for those
who cannot remember.”
Jim Fruchterman, 2007 MacArthur award recipient
