Labor saving machinery doesn't work when trying to learn a subject.
Taking notes during a lecture is a neat trick to force the content to stay in short-term memory for at least a little while. But that also comes with the risk of transmission errors. Instructor-provided lecture notes can serve as a canonical reference. As long as you don't treat them as a labor-saving device, but instead as an error-correcting mechanism, they're helpful.
