I think that's a hard argument to make when Encarta 95 was more advanced than this. I'm all for making information public, but a video of the presentation that's not searchable, can't skip from slide to slide, doesn't show the presenter, doesn't have an index, can't click on links etc. isn't exactly the future. And with all the information available these days the standard should really be higher.
Are you so sure that the learning style you seem to prefer is really ideal for all people? Because you sound really sure, but I'm not sure how that could be.
There weren't really an alternative, so whether the format has endured or not isn't really relevant. Many other schools are doing this differently. At this point your statement about "holding back the progress of an entire society" seems rather hollow. I can't convince you data exposing data is more useful, but I also shouldn't have to. It's one of the fundamentals of computer systems if not the Internet.
In this case a reasonable response from society, for example, may have been "ok UCB how much will it cost you to sub those? alright, we'll give you the funds from tax money." Lacking such a response all UCB could do was go "oh society, you don't want to help? then you don't get to keep this."
Keep in mind that only a short-sighted person would say UCB messed up here. They didn't. The USA as a whole messed up, so the USA as a whole gets the stick.
That's a hard argument to make too. Some of the people that may have learned from these lectures might go on to champion disability rights, or may go on to invent tech that may address some of those disabilities. We simply can't all progress in lockstep, and trying to force that is probably harmful to all.
While I can sympathize, I'm not sure holding back the progress of an entire society just to not disadvantage a subset of it is as reasonable as you seem to think. I agree that a better solution would be ideal though.
Perhaps they should just fund a machine learning program for closed captioning, instead of punishing people who are advancing social interests.
