I think I disagree with Marcus here: JetBrains Connect, Ep. 5 – "DSLs: Bringing the Experts into Development" Markus Völter, Václav Pech - YouTube
I think BSLs “Brain Sucking Languages” is an expressive compact way of describing subject matter experts developing software. 
@voelter / @vaclav.pech , I’ve really enjoyed a lot listening to you in that talk. I think that for people like me, that have no idea about this subject, the talk was a very good introduction.
Great work!
