But on a more serious note, I don't really agree. Writing more code needs to be a conscious choice, but going for the shortest code too often creates a mess. I know, since I was that junior dev who just wanted to get stuff done and I would ignore project architecture in order to have to implement less, like accessing the database in GUI code.

Shorter code with the same amount of coupling between components and with the same readability is always better though.
