r/MachineLearning - [D] "A.I. Is Harder Than You Think" (Gary Marcus again ...)

My initial uncharitable take was: College profs need to understand product development is harder than they think. A number of points here indicate a lack of progress on general AI by pointing to product decisions that would be present no matter the implementation. He seems to then use this as a rallying call to encourage going back to knowledge engineering circa late 80's early 90's? I'm going to guess i'm missing something. Yes general ai is far away.
