I'd agree if you'd say that the Stuxnet operation was very sophisticated. That is, coming up with a plan, infecting the right machine in the right plant at the right time so an unknowing technician would accidentally become a carrier for it, then finding a way to make him drop by at the target next, learn enough about the target without having access to be able to write code to identify it with confidence among lots of similar machines etc, but most of that is classical intelligence work and has nothing to do with programming, tech, or Stuxnet specifically. If someone sews on a hidden pocket to a jacket to be used in an extremely complex intelligence operation, that doesn't make it "the most sophisticated seam in history".
