Judging AI by what happened in the 1980s is like judging our capacity for space flight by Otto Lilienthal.
The anecdote is to illustrate that, no matter what “miracles” are produced, we still don’t know whether AI is a million monkeys writing shakespeare.
When man can create an AI that produces close-to infallible work, and then the men can explain how the machine rationalized the answers, I’ll be impressed. I’m not saying that man has to be able to predict the answers - just that they have to be able to see a rational thread from start to finish.
