It isn't a throwaway comment, it is reference to writing and work she has been doing for quite a while. It does come across as fairly arrogant without the context of all her other writing and work. With that context it comes across to me as more of an expression of frustration.

Yeah, but if you've followed Hossenfelders writhing you know that it's been wobbling along the line between relevant critique and pure clickbait for over a year now.

This is likely the first time I've seen any claim that she has a good idea of what to do instead (she's had the idea before, but not claimed it to be a good one as I recall), the past year it's been mostly about how all other physicists are stupid... and it's not like this supposedly "superior" strategy has yielded any great advanced for in her work.
