It sort of is, indirectly, and I agree with pretty much everything.
But the bit about sycophancy was particularly enlightening. I actually thought "plain" ChatGPT-like interfaces could be good for learning. But the Youtube ROAS example is really powerful. If the student can skew the teacher's conclusions so much just by the way they phrase their questions/answers, we're going to mislead new programmers en masse.
I'm not even sure that the extensive prompting they say they use for their "Boots" is good enough.
I guess in the age of AI you still need someone to repeatedly reject your pull requests until you learn. And AI won't be that someone, at least for now.
