Optimistic science fiction shows humanity applying unique ingenuity to solve tough problems. Our lived reality today is that we already know the technical solutions to many tough problems (hunger, homelessness, many diseases, overpopulation, climate change, war) but simply refuse to apply them. Of course people don’t believe optimistic sci-fi anymore.<p><i>Star Trek</i> the original series is usually taken as an example of optimistic sci-fi. It’s set in a faster-than-light space ship, so it’s science fiction. But the optimism came primarily from the back story: having solved our problems on Earth, and created a peaceful society of plenty, humanity turned its thoughtful minds to exploring the stars.<p>Does that seem like the track we are on?<p>Science fiction, to be optimistic today, needs to show how our society gets from here to there. Social progress was taken for granted in the latter 20th century. It’s not anymore. Something is stopping us, something beyond science and engineering. In fact whatever it is, is driving us to actively attack and destroy the science and engineering we have already developed.<p>A better future is going to take something else: culture, or society, or kindness, or empathy. It will take choice, and effort, not antimatter and phasers.
