I think there's an urgency in writing on physical paper which can't be ignored. I don't like the way that the computer forces you to second guess everything before it's even halfway done. The reason that well-known writers put everything down on paper first is because they understand the need for agency, in order to get the right amount of unquestioned pages sometimes you have to practice the flip and forget.

Writing on computers just leads to shorter sentences and ridiculously manicured passages. The rough life is excised before it has a chance to show promise, and the book turns into some kind of boring deep-think equation. A complicated literary puzzle. Not worth reading. Have fun with your moleskine!
