I took me some reflection and some education from the comments here to see this, but it seems like Powell had the same pique to the interviewer's questions as he did to his colleague's. So he answers the questions, but at the same time he critiques the interviewer:
- "I now lack the juice to fuel the bluster to conceal that I am a simpleton," suggesting that the interviewer still has said juice. This also allows some subtle critiques like "I'm ignorant of 'malapert'", which on the surface is a sort of back-handed compliment to the questioner on their ability to coin a phrase like "malapert urbanity" that a "simpleton" like they are interviewing does not understand. But it also suggests that if the "legend" they are interviewing does not know the word, perhaps this is excessive juice.
- "It emerges with no consideration for anything but the next correct word." Questioner, stop overthinking things.
- Then when the interviewer asks Powell to agree with his assertion-as-a-question that there is no wrong way to read a book, Powell responds with a story about how he wants to focus on making writing better but people like the interviewer that say there are no wrong ways to read a book are actually teaching that there are wrong ways to say things. Furthermore, people like the interviewer eviscerated a recent book in the style that people like the interviewer celebrated, on the grounds of racism, despite the fact that the content of his books is from actual black people who said those things. So the implied answer the question is that no, a book does not get unmoored from its time period, because he cannot actually publish those books today, and that there may or may not be a wrong way to read a book, but there certainly is a wrong way to write one, namely his (celebrated) way.
But then it all goes completely over the interviewer's head (no doubt as expected). I wasn't impressed with Powell on the first read, but wow, that is some finesse!
