From Ted Hughes’ 1995 interview with the Paris Review, discussing the different yields of writing tools:

I made an interesting discovery about myself when I first worked for a film company. I had to write brief summaries of novels and plays to give the directors some idea of their film potential—a page or so of prose about each book or play and then my comment. That was where I began to write for the first time directly onto a typewriter. I was then about twenty-five. I realized instantly that when I composed directly onto the typewriter my sentences became three times as long, much longer. My subordinate clauses flowered and multiplied and ramified away down the length of the page, all much more eloquently than anything I would have written by hand. Recently I made another similar discovery. For about thirty years I’ve been on the judging panel of the W. H. Smith children’s writing competition. Annually there are about sixty thousand entries. These are cut down to about eight hundred. Among these our panel finds seventy prizewinners. Usually the entries are a page, two pages, three pages. That’s been the norm. Just a poem or a bit of prose, a little longer. But in the early 1980s we suddenly began to get seventy- and eighty-page works. These were usually space fiction, always very inventive and always extraordinarily fluent—a definite impression of a command of words and prose, but without exception strangely boring. It was almost impossible to read them through. After two or three years, as these became more numerous, we realized that this was a new thing. So we inquired. It turned out that these were pieces that children had composed on word processors. What’s happening is that as the actual tools for getting words onto the page become more flexible and externalized, the writer can get down almost every thought or every extension of thought. That ought to be an advantage. But in fact, in all these cases, it just extends everything slightly too much. Every sentence is too long. Everything is taken a bit too far, too attenuated. There’s always a bit too much there, and it’s too thin. Whereas when writing by hand you meet the terrible resistance of what happened your first year at it when you couldn’t write at all… when you were making attempts, pretending to form letters. These ancient feelings are there, wanting to be expressed. When you sit with your pen, every year of your life is right there, wired into the communication between your brain and your writing hand. There is a natural characteristic resistance that produces a certain kind of result analogous to your actual handwriting. As you force your expression against that built-in resistance, things become automatically more compressed, more summary and, perhaps, psychologically denser.
