Natural Correction

People talk about making computers easier to use, but it usually ends up that humans are made easier for computers to use.
Take the keyboard, for example. Among people who type, it's sadly acknowledged that in 20 years our arms will be permanently warped and twisted from the repetitive impact inflicted by today's keyboards. We've been promised everything from voice input to brain-computer interfaces, but whether due to neglect or lack of knowledge, none of these technologies ever seems to work.
Instead, people wear braces, grab at wrist rests, and give away squishy balls at trade shows.
Sure, someday voice recognition will work. But by then, biology will have corrected and selected those uber-arms of our future; one day, evolution will yield comfort.
