I think competition can make people stronger at whatever it is they're competing on. If we're competing in some athletic event for competitive swimmers, really intensely competing, it's likely that both of us will become better, but it's also quite possible we'll lose sight of what's truly valuable.

I want to tell mayors, county chiefs and heads of big companies: don't just chase GDP growth; don't chase the biggest profits at the expense of our children and grandchildren and at the cost of sacrificing our ecological environment.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
