The “Darmok” reference in Temba, seine Arme weit!, that is. Well, combined with the additional German “Sinnlos im Weltraum” reference it sure was… cryptic.
As for the general recognition of the specific Star Trek: TNG episode, well, take a look at this recent TEDx talk by Scott Hanselman! :)
Anyway, it’s a great talk, go watch it!
