alt Hacker News> You essentially coupled "I used to do this thing, and now I'm really credentialed but I don't do this thing any more" with "the ones most capable of elucidating existing ideas can be the ones least motivated to do so."
I read that as a reference to Dunning-Kruger.
The second statement could, standing by itself, certainly be a reference to Dunning-Kruger.
In which case, I'm not sure how you read the first statement other than "I'm at the high end of capability on the Dunning-Kruger curve."
