Eesh, sorry! I'd like to think it's a Medium problem — either that or your browser decided my article wasn't worth reading ;)
I think in terms of development I think its good to have a good idea what's going on end to end, I would consider that normal. However, its good to have a specialism too, that is be a master of one or two things. Its not much to ask someone to be proficient in a programming language or 3 and a database of some description, I don't think.
Oh... and the content is good too ;)
