> a few years ago the degree of interpretability we have today (thanks in no small part to Anthropic's work) would have sounded crazy

My understanding is that a few years ago, if we knew the degree of interpretability we have today (compared to capability) it would have been devastatingly disappointing.

We are climbing out of the trough of disillusionment maybe, but to say that we have reached mind-blowing heights with interpretability seems a bit of an hyperbole, unless I've missed some enormous breakthrough.
