Computer assisted thinking
There are things a computer gives you, that paper and pen don’t, such as speed and flexibility. It’s one thing to write a shopping list on a piece of paper. Even though I wish my wife would arrange the lists she writes to me in the order of the physical location of the items in the store, it just doesn’t happen. Once you write something down on paper you don’t do much editing, simply because it’s too much trouble. On the computer things get much easier. Moving items around, editing, reordering, at the speed of your thought. Well, almost anyway, and after you’ve got some practice.
