Finally got around to reading this completely. Great exposition.

[T]oward the beginning of my rationality training, I went through a long period of being so enamored with a-veridical instrumental techniques [...] that I double-thought myself into believing accuracy was not so great. But I was wrong. And that mattered. Having accurate beliefs is a ridiculously convergent incentive.

It reminds me of Wittgensteins ladder: You seemed to have stepped up the ladder thru practical rationality and dark arts and by no longer need them explicitly. You have unconscious competence.

I wonder if it just coincidence that there are also Four Stages of Competence.
