Writing notes by hand has been proven to increase understanding and retention. Unless we’re giving kids OCR tablets, they’re learning less taking notes on a keyboard.
I believe this train of thought jumped to a conclusion not supported by the evidence: does taking notes on computer not increase understanding and retention?
Because anecdotally: I retain more when I take notes on laptop than if I took no notes. I also retain more when I take notes on laptop than if I took notes on paper because my typing speed can keep up with the topic and my writing speed cannot.
To support your claim see Mueller & Oppenheimer's research from 2014. The big issue is that while the laptop lets people capture MORE of the words said, the process of filtering is how the mind consolidates information. Taking notes require you to decide what to leave out and that is what helps you remember.
