There are proven advantages to hand-writing out notes and planning on paper over digital tools - the physical, tactile experience engages your brain in different ways, and this has been proven by multiple studies.
Digital tools are great. They're why they're here. But a lot of people want paper for good reasons, and it's a very different experience to wanting a wooden holder for your phone.
I agree on the benefits of tactile experience. But it need not come from paper, which is very modern thing. Information is being sucked out from real world, into digital space. College teachers are no longer writing on blackboards. Money is no longer a physical thing. Work is being done in virtual spaces. The only things that are left in physical world are the information-less objects, just like how the world was before invention of writing.
When information finds its natural habitat in the digital space, we need to re-orient ourselves.
