That knowledge is pretty hard to come by even if you know how to code, so not having thought computationally .. ever .. makes for a really bad PM. Computational thinking and prototyping skills are the key, even if you use another human to do the prototyping, knowing what to bother protyping and how to learn from the prototype are all very important for a PM. If you dont have those skills, you don't have the means to discover the limits of what you know about the area your product grapples with, and to grow. Steve Jobs, I believe, was very good at both.
