Susan Fowler is legit terrifyingly brilliant. In only a year and a half she went from pre-algebra to grad QM while being a writer at NYT. Some people are just set to a higher gear.
I found this hard to believe, so I looked it up. It appears she _did_ go from pre-algebra to grad quantum within a short time [1], but that was many years before she joined NYTimes in 2018.

— blurb for her book “Whistleblower”
You quoted a marketing blurb. Of course it is supposed to sell the author.
