I had first noticed "meticulous" to be used a lot in translations from chinese. Is it sth about chinese itself (that they use sth a lot for which meticulous is the closest translation), or about some translation software that is possibly biased towards such buzzwords when translating to english?
ESL here, not Chinese. I find meticulous to be a perfectly normal word, I think I don't really use it, but I think I read it from time to time, but maybe I just read some sort of publication by a fan of the word? :) Same for surpass and boast, I think I use "surpass expectations" and I had to think for a moment, I would use 'brag' these days but pretty sure in school I learned boast, which sounds more formal BE to me…
ChatGPT, of course, behaves like its training set...and the majority of that set is professional writers' published works, which would be more likely to use words like that. It's a collision of academic and literary writing styles with the expectations of people who think Harry Potter or the New York Times (which specifically targets a fifth grade level, placing them above other papers) are challenging reads.
