I think like many things, it's not universally true. At least for me I'm a really slow writer (and poor spelling), that if I were to hand write notes in a lecture, I'd focus on writing and miss half of what is said, and fall behind to the point that something I was copying from the board gets wiped off.
Maybe typing isn't ideal, but it's the better of the 2 options for me.
