Artificial intelligence is growing up fast, as are robots whose facial expressions can elicit empathy and make your mirror neurons quiver.

Flying has changed how we imagine our planet, which we have seen whole from space, so that even the farthest nations are ecological neighbors. It has changed our ideas about time. When you can gird the earth at 1,000 m.p.h., how can you endure the tardiness of a plumber? Most of all, flying has changed our sense of our body, the personal space in which we live, now elastic and swift. I could be in Bombay for afternoon tea if I wished. My body isn't limited by its own weaknesses; it can rush through space.

I'm an Earth ecstatic, and my creed is simple: All life is sacred, life loves life, and we are capable of improving our behavior toward one another. As basic as that is, for me it's also tonic and deeply spiritual, glorifying the smallest life-form and embracing the most distant stars.

Our sense of safety depends on predictability, so anything living outside the usual rules we suspect to be an outlaw, a ghoul.

Working from home meant we could vary snack and coffee breaks, change our desks or view, goof off, drink on the job, even spend the day in pajamas, and often meet to gossip or share ideas. On the other hand, we bossed ourselves around, set impossible goals, and demanded longer hours than office jobs usually entail. It was the ultimate "flextime," in that it depended on how flexible we felt each day, given deadlines, distractions, and workaholic crescendos.

So before I start work on a book, I'm like a pregnant mole - I obsessively tidy and order my closets and everything in my study. Because there's such a cascade of images and ideas that I'm grapping with mentally, I couldn't also be in a chaotic setting.

We tend to think of memories as monuments we once forged and may find intact beneath the weedy growth of years. But, in a real sense, memories are tied to and describe the present. Formed in an idiosyncratic way when they happened, they're also true to the moment of recall, including how you feel, all you've experienced, and new values, passions, and vulnerability. One never steps into the same stream of consciousness twice.
