For me pen and paper being beneficial is a strong signal of an interesting project.

A large part of day-job work doesn't deserve the pen and paper - We just need to track TODOs, links and some other bullet points for them. Digital tools are very good at these because it's optimized for them.

On the other hand, if a problem demands the flexibility and the visual capacity of the pen and paper, it's a good sign of the sufficiently large intellectual problem space it contains.

Great point here. I recently was fascinated by a new topic and filled two notebooks of 200 pages with my notes written with a fountain pen.
