I went to college before laptops as well. Taking notes has two purposes. First to remember what was said in class, extras that are not in the book, and it's a good indicator of the exam questions. Second is processing what is said. Research has shown that writing down what you hear makes you better understand and remember what is said, then when you type it on your laptop.
Even if you don't use the notes afterward, they are still useful. Video is a very useful method, but then the video has to be edited, or do you get three simultaneous streams, one of the professor, the board and the powerpoint? Videos like on Udemy are made for the medium. Class is not made for video, and I wonder how productive those videos are.
And when you go to class, do you really go home and see the whole class on video once again? That's way too time consuming. The notes are a good summary, much faster. Yes and it is taking effort, exactly what is needed. It puts your mind to work.
