The stupid interface is the most usable

“.. every decade since the ’80s, billions of dollars and gazillions of man-hours have been invested in this fundamental error, to end routinely in disaster. It’s as though the automotive industry had a large ongoing research program searching for the perpetual-motion engine.
The error is that control interfaces must not be intelligent. Briefly, intelligent user interfaces should be limited to applications in which the user does not expect to control the behavior of the product. If the product is used as a tool, its interface should be as unintelligent as possible. Stupid is predictable; predictable is learnable; learnable is usable”
