I still get IEEE Trans. on Control Theory, and it's all machine learning now. Except that the controls people are desperately trying to solidify the underpinnings of machine learning, so that control systems don't suddenly misbehave for some sets of inputs. Controls people want a guarantee that if it does something reasonable for inputs of 5.1 and 5.2, it doesn't do something completely unexpected for an input of 5.15.

Reminds me of my favorite abstract, from John Doyle's paper "Guaranteed Margins for LQG Regulators".
