Software is a tool, ORMs are tools. I don't need a tool to do my work for me, I just need it to work well for whatever job it's for. A "stupid" hammer would be one that is just a rock with a hole in it loosely fitted over a stick that fits in the hole with nothing but friction to hold it on. A "stupid" farm tractor would be one that gets 15 mpg most of the time except when it's used during a full moon between 10am and noon, in which case it gets 1 mpg.

Most ORMs are indeed stupid. They often produce completely surprising results at the least opportune moments. They are high maintenance tools that require constant supervision to ensure that you haven't accidentally made some changes which causes something crazy to happen in the ORM. It's about the principle of least surprise, which ORMs often fail horrifically at.
