I'll delete it myself if you'll explain exactly what's so objectionable.
I watched this video for 30 seconds and it is not good content.
I would rather read an article about the sequential subset of Erlang oppose to this garbage.
Apparently, I am not alone.
God knows how it got to the top of HackerNews - slow Sunday night maybe?
In short: There's no need to "do a little better job of relevance in the beginning" because a.) the video is almost thee years old and b.) people liked it that way.
Incidentally I looked up the word for German "Fachidiot", and the dictionary said "nerd" :-/ ("Fachidiot" in German is someone who is very good in his chosen profession, but completely clueless about everything else - to the point of making idiotic decisions for lack of broader vision).
