As someone who likes to "get under the hood", I'm used to grumbling about developers these days who just glue together existing frameworks.

But the real cause of my dissatisfaction is that I find it harder to glue together existing frameworks -- I don't know where to begin, until I've dug in a bit to find out how something works underneath. Meanwhile other people whose approaches I think of as simplistic are able to leap in and get things done more quickly than I can.

(Similarly I find it almost impossible to learn much of a foreign language without studying the grammar, while some other people can immerse themselves and become quite conversant without ever thinking about grammar.)

Maybe the "non-engineer" developers are just working at a higher, and more immediately useful, level of interpretation.
