My latest essay for Aeon magazine asks when it’s ethical to hand our decisions over to machines, and when external automation becomes a step too far. The first few paras are below: read the rest on the magazine’s site.
For the French philosopher Paul Virilio, technological development is inextricable from the idea of the accident. As he put it, each accident is ‘an inverted miracle… When you invent the ship, you also invent the shipwreck; when you invent the plane, you also invent the plane crash; and when you invent electricity, you invent electrocution.’ Accidents mark the spots where anticipation met reality and came off worse. Yet each is also a spark of secular revelation: an opportunity to exceed the past, to make tomorrow’s worst better than today’s, and on occasion to promise ‘never again’.
This, at least, is the plan. ‘Never again’ is a tricky promise to keep: in the long term, it’s not a question of if things go wrong, but when. The ethical concerns of innovation thus tend to focus on harm’s minimisation and mitigation, not the absence of harm altogether. A double-hulled steamship poses less risk per passenger mile than a medieval trading vessel; a well-run factory is safer than a sweatshop. Plane crashes might cause many fatalities, but refinements such as a checklist, computer and co-pilot insure against all but the wildest of unforeseen circumstances.
Similar refinements are the subject of one of the liveliest debates in practical ethics today: the case for self-driving cars. Modern motor vehicles are safer and more reliable than they have ever been – yet more than 1 million people are killed in car accidents around the world each year, and more than 50 million are injured. Why? Largely because one perilous element in the mechanics of driving remains unperfected by progress: the human being.
