My fiancée recently remarked that she'd been doing more writing on paper because it made her more productive. She theorized that she takes an editor's mindset in the face of WYSIWYG renditions of her spelling mistakes. The same goes for her design work. The industry tools make it too easy to recognize "wrong" as it's happening. That sounds like a singing endorsement of these tools, but our experience working with lower-tech tools has informed a different conclusion. You're not being "helped" to see "wrong" in what you do, you're being cut off. Your generative, creative mode is being inhibited.
