It's one thing to notice that beginners can sometimes make contributions by luck, just by not knowing how hard something is supposed to be. It's another to use this reasoning to glorify lack of knowledge.
Whenever I see someone succeed rapidly I assume it isn't a newcomer, that there are depths of effort I cannot yet see.
Many, many people have gone into the field to study the traditional techniques, and glorifying this knowledge has not led to AI.
I don't think a beginner is going to create AI by "luck". But a beginner's mind is not cluttered in the same way as an expert's. This may be what it takes to get working AI.
Expert knowledge is appropriate when discussing proven solutions. AI is speculative at this point.
