I'll argue that it's stupid that the law requires Berkeley to make its content accessible. If accessibility is something society has determined is worthwhile (I think we can all agree that it is), then it should be funded by society. Unfunded mandates are no way to run society.
Now if someone can make technology to make that accessible, post-hoc, awesome. And if someone can make it easy for the content to be born accessible, even better! But I do not agree with making accessibility required.
And not just accessibility for blind people, of course. And here I have to be honest and admit that I haven't lived up to this ideal myself. Several months ago, I gave a presentation to a local Meetup group for software developers on making software accessible to blind people. It's on YouTube. But I haven't yet had it captioned so a deaf person can benefit from it. Nobody's coming after me with a lawsuit in hand. But now that I've thought of this, I should get that video captioned.
Or maybe the presentation or lecture itself is an archaic way to share information. You can see it in the word "lecture". It comes from reading, as in reading out loud. But the people who attend today's lectures can read for themselves. Maybe the best way for content to be born accessible is just to stick to electronic text, that everyone can read in their own way and at their own pace.
