Could anyone explain what Dijkstra meant by

>It is misleading in the sense that it suggests that we can adequately cope with the unfamiliar discrete in terms of the familiar continuous, i.e. ourselves, quod non. It is paralyzing in the sense that, because persons exist and act in time, its adoption effectively prevents a departure from operational semantics and thus forces people to think about programs in terms of computational behaviours, based on an underlying computational model. This is bad, because operational reasoning is a tremendous waste of mental effort.

I don't get the part where thinking in terms of computational behaviors throws something off (and more).
