Many people who are, or who regard themselves as, experts in their subjects are poor at teaching or explaining it.
This could be behind many of the “Why do you want to do that?” style responses.
The other common one being, “It’s easy! Anyone can do it!” followed by a lightning-speed demonstration or a torrent of jargon, that leaves the hapless enquirer feeling right daft and certainly none the wiser.
In both cases the speaker is unable not only to comprehend the enquirer finds the subject hard, but also to explain it clearly. (My school O-Level Maths teacher exemplifed these faults, helping me stay highly innumerate. He helped and encouraged only those who found maths easy to learn.)
I don’t know if AI can be like that
