The OP asked about "technical resources" to get knowledgeable "in the relevant technologies", and continued to make it clear that this was about learning to actually use the technologies. That is the wrong approach.
The poster said no such thing. Instead he said:
So the OP was specifically saying he didn't think the right approach was for his friend to learn how to actually implement anything in these technologies. He then later asked whether he was correct in saying his friend should NOT learn how to implement the technology itself:
Do you even agree that this is an appropriate approach or should he look to develop a working knowledge of these languages instead? Any other suggestions on how to approach this?
So all in all, the OP was trying to find the best solution overall, and did not think that his friend should actually learn the ins and outs but was open to any advice whatsoever. Everyone just assumed that this guy is like all their old PHBs that tried to pretend like he knew what he was doing.
