I've direct experience on the power of handwriting to memorise concepts. When at the UNI, I was studying CS (while working part-time) less than 10 ya, and classes where full of laptops. I was take notes during lectures using only pen and paper and similarly I was taking my notes about the main concepts from the courses books. Then I was re-writing them again in a more summarised way, and then underline this notes and study all together. The power of handwriting is real and I'm still taking notes and keeping a journal nowadays.
It's sad that this incredible ability of our brain to learn concepts from the small movement of our hands, probably sculpted by our evolution, is going to get lost in future generations. This is because companies are making deals with schools to provide them software and devices. In a better world the school system would be one of the top 2 priority of every country, and receive adeguate public investments to don't have to adapt their education systems at companies product, to satisfy the greediness of entrepreneurs and investors.
Don't abandon pen and paper, don't regress human brain capacity.
