Status-Q

Here’s a (slightly tongue-in-cheek) idea after chatting with a vicar friend the other night…

Writing sermons is a time-consuming business. Not all clerics are particularly good at it, and there’s a long tradition, in certain circles, of reading other people’s classic sermons to your congregation, or re-using your own ones in other places. Has this been brought up to date?

Somebody should create, if they haven’t already, an online repository where you can upload your sermons, in text, audio or video form. They would be searchable by subject, biblical reference, etc and you would be free to download others and deliver them yourself. The only obligation would be that somewhere (e.g. on the service sheet) you would have to acknowledge your source: ‘Based on SermonSite sermon 4569 by Revd Joe Bloggs.’ You could then provide feedback, further notes, and ratings. More importantly, any members of the congregation who have downloaded the SermonSite phone app could also rate it, and Joe Bloggs would get appropriate credit.

Sermons that achieved a high-enough rating might migrate into the ‘SermonSite Pro’ category, where they were only accessible to those paying a larger subscription, and where the authors could be compensated for their use. Vicars who proved particularly gifted at this sort of thing could be commissioned to provide exclusive material for Sermonsite, so supplementing the meagre income provided by most ecclesiastical institutions, and so on…

Of course, I’m a bit out of touch, but I imagine that the average sermon-listening congregation these days doesn’t contain a high proportion of people who know how to download and use smartphone apps. That could be a problem.

Still, I offer the idea for what it’s worth. Maybe it’s something to think about, say, during a dull sermon…

SermonSite: Bringing the most powerful preaching to a pulpit near you.

I found an iPhone this morning… a very elderly one, with some inkstains on it. It was locked, but I managed to unlock it with the code 1415. The first thing I did was to ask Siri a question about what the owner might have been doing just before he lost it…

Today is the 600th anniversary of the Battle of Agincourt.

Thanks to Richard Owers for pointing me at an article from the MIT Technology Review entitled Why Self-Driving Cars Must Be Programmed to Kill. (Doesn’t that make you want a custom licence plate on yours? BOND007 – programmed to kill?)

We talked earlier about the ethical challenges of driverless cars and how many of these are variations on Phillipa Foot’s classic Trolley Problem.

The MIT article takes it further and raises a nice conundrum or two:

How should the car be programmed to act in the event of an unavoidable accident? Should it minimize the loss of life, even if it means sacrificing the occupants, or should it protect the occupants at all costs?

As they point out, who is going to buy a car which is programmed to sacrifice its owner?

Here is the nature of the dilemma. Imagine that in the not-too-distant future, you own a self-driving car. One day, while you are driving along, an unfortunate set of events causes the car to head toward a crowd of 10 people crossing the road. It cannot stop in time but it can avoid killing 10 people by steering into a wall. However, this collision would kill you, the owner and occupant. What should it do?

One way to approach this kind of problem is to act in a way that minimizes the loss of life. By this way of thinking, killing one person is better than killing 10.

But that approach may have other consequences. If fewer people buy self-driving cars because they are programmed to sacrifice their owners, then more people are likely to die because ordinary cars are involved in so many more accidents. The result is a Catch-22 situation.

One way to approach this is that adopted by a group at the Toulouse School of Economics. They used ‘experimental ethics’, which roughly means crowd-sourcing the answers to difficult questions and seeing what the majority think.

In general, people are comfortable with the idea that self-driving vehicles should be programmed to minimize the death toll.

Makes sense, but…

“[Participants] were not as confident that autonomous vehicles would be programmed that way in reality—and for a good reason: they actually wished others to cruise in utilitarian autonomous vehicles, more than they wanted to buy utilitarian autonomous vehicles themselves”

Ah – understandable, I guess! And…

If a manufacturer offers different versions of its moral algorithm, and a buyer knowingly chose one of them, is the buyer to blame for the harmful consequences of the algorithm’s decisions?

Lovely stuff. I wonder how we’ll deal with this.

Of course, some of these kind of decisions are always being made by anyone building or using potentially dangerous machinery. Did your car’s manufacturer install the most expensive and reliable braking system available when they built your car, or did they base their decision partly on cost? Perhaps they did so to spend more money on the airbags, which protect the occupants instead of pedestrians and cyclists?

Similarly, those who design medical systems, drug-dispensing machines, prescription printers, and so on make decisions which could be life-or-death ones, and we somehow cope with that. But the driverless car does throw some of these questions into sharp relief.

Update: thanks too to Laura James who pointed me at the Principles of Robotics.
