We wanted to solve robot problems and needed some vision, action, reasoning, planning, and so forth. We even used some structural learning, such as was being explored by Patrick Winston. – Marvin Minsky
There was a failure to recognize the deep problems in AI for instance, those captured in Blocks World. The people building physical robots learned nothing. – Marvin Minsky
If you just have a single problem to solve, then fine, go ahead and use a neural network. But if you want to do science and understand how to choose architectures, or how to go to a new problem, you have to understand what different architectures can and cannot do. – Marvin Minsky
Societies need rules that make no sense for individuals. For example, it makes no difference whether a single car drives on the left or on the right. But it makes all the difference when there are many cars! – Marvin Minsky
