Factory settings—a contemporary synonym for fate. My friends, family and acquaintances all had appeared in my life with fixed settings, with unalterable histories of genes and environment. I wanted my expensive new friend to do the same. Why leave it to me? But of course I knew the answer. Not many of us are optimally adjusted. Gentle Jesus? Humble Darwin? One every 1,800 years. Even if it knew the best, the least harmful parameters of personality, which it couldn’t, a worldwide corporation with a precious reputation couldn’t risk a mishap. Caveat emptor.
