Chapin isn't against note taking. Chapin is arguing that any note taking system should be kept simple so administering it does not becomes a clever way to distract yourself instead of doing real work. Note taking could be procrastinating, in other words.

I get the point. Larry David of Curb Your Enthusiasm and Seinfeld keeps a small paper journal in his pocket for jotting down notes. An extreme example of note taking is probably the guy who spends all his time trying to photograph and video tape his vacation to the point that he isn't actually "present" to enjoy his own vacation.

tldr: Be careful your note taking doesn't interrupt and degrade your creative "flow" and resulting output
