Case overblown
The real trouble in this field is the way it is reported by the media and the marketing departments of big corps. From one side the label AI is usually assigned prematurely, from the other side any misstep is painted as the big disappointment of the whole field. AlexNet maybe one of the fist implementations with some successful applications, something similar is now used by google image search, but it is not the only one and it does not represent all CNNs. E.G.CNNs trained on MNIST definitely do not depend so much on texture.
