Indeed, and one of its initial and still strong missions is to bring the benefits of rapidly developing science and engineering to the world. As far as I know, the single biggest boost to health and material well being in the US occurred in the post-Civil War period, not much later when we got "modern medicine" as in antibiotics (although what they could often pull off with antiseptics and infection control was amazing, read a history of the Mayo brothers if you're interested).

But we're talking about gross ingratitude here. That OCW is not perfect in this is a crime (literally, unless you think they can get away with ignoring a civil legal settlement or judgement), with a punishment requiring either removing the videos or spending a lot of money it and MIT doesn't have to perfect them under an inflexible legal mandate.

I again repeat, this is not going to end well. Especially for the truly deaf people this is ostensibly being done for.
