At my school CS majors actually take more math than most engineering majors.
Human limitations and fallibility have nothing to do with economics in particular.
That is correct and is not contradictory to the quote. The point of the quote is that economics can help show leaders how little they really know about the impacts their policies will have.
As for the rest, you have presented a false dichotomy. Hayek didn't say that we shouldn't do anything unless we are 100% sure of all of the consequences of that action. He did say that we don't know nearly enough about economics to justify making grand designs to control the economy. This applies equally to many regulatory schemes. The bulk, but not all, of such things are best left to emergent systems that contain local knowledge that are, currently, inaccessible to central planners.
He who steps on others to reach the top has good balance.
