Eric San

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.

Writers displace their anxiety on to the tools of the trade. It's better to say that you haven't got the right pencil than to say you can't write, or to blame your computer for losing your chapter than face up to your feeling that it's better lost.
