No, it's more of a subtle, inflationary pressure.
For me, it's the act of writing, the memory it helps solidify, and... being an FP nerd.
Can I take notes on a phone? Sure, but I wouldn't use a personal device for work notes, ever. Between my privacy, customer privacy laws, and separation of concerns. I've no compunctions at all, though, about sharing an A5 notebook between journal, work notes, personal notes, and reminders.
