Why some body rich? Why not start NGO like website for this? each of us,would contribute a little bit 1$. And that site would have investment to recurit people for subtitling.

Is this idea feasible?

P.s. Your idea completely makes sense. I wish google instead of wasting money in many different ways(for example starting cs education site , which of course will be not even close to what Berkeley offers) would do this. Anyone would do this ,would become my here, literally.
