I think that was more a comment on people who go "It seemed hard at first, but after a week it was totally natural and I hardly ever even think about the borrow checker anymore."
Neither it has been mine. I have written C and C++ only in college, so my impression might be very wrong, but I think that programmers who are proficient in low level languages are the ones that learn Rust the fastest due to the low level concepts Rust's compiler puts upfront such as sane memory management.
