I have the same feeling about a lot of productivity tooling in the software world. At one point I had been convinced by several people that I needed to be taking notes, either handwritten or have some kind of note taking system. I tried for a good amount of time (2 years) before concluding that it's not for me. I'm more productive without notes, my mind seems fairly well organised. My biggest enemy is procrastination, not disorganisation.

So that's all well and good. I don't believe that my way is the one true way, I think each to their own. What I don't like is that people won't stop telling you about their note taking systems and that you should take notes. Well, things have calmed down a bit now, but a few years ago it felt like people would actively hunt you down and force their note taking opinion on you if they suspected you didn't keep your own knowledge base.
