tank remembers going to a pig roast out in the country where the host took him to a barn and showed him an experimental perceptron machine built in rosenblatt's lab it had all of these tubes and wires and it was just gathering dust Around the same time, Tank read Rosenblatt's 1962 book, Principles of Neurodynamics.

It was basically the first textbook on artificial neural networks, and it's an inspirational book in many ways, an absolute classic, says Tank, who became a leading AI innovator at Bell Labs and co-founded the Princeton Neuroscience Institute.

What happened between the Beatles' haircut lesson and the age of modern AI? For years, it seemed as though other forms of machine intelligence would win out.

Rule-based logic, for instance, used individually coded if-then instructions to build an elaborate flowchart.
