I gave this speech as the closing keynote at A11yQC, a conference on Web accessibility, on 14 October 2014 in Québec City, Canada. I have published my script here as the slides can’t really convey its message on their own.
We, as an industry, tend to have a pretty myopic view of experience. Those of us who work day-to-day in accessibility probably have a broader perspective than most, but I would argue that even we all fall short now and again when it comes to seeing the Web as others do.
