How Do We Program Moral Machines?
nicholast writes "If your driverless car is about to crash into a bus, should it veer off a bridge? NYU Prof. Gary Marcus has a good essay about the need to program ethics and morality into our future machines. Quoting: 'Within two or three decades the difference between automated driving and human driving will be so great you may not be legally allowed to drive your own car, and even if you are allowed, it would immoral of you to drive, because the risk of you hurting yourself or another person will be far greater than if you allowed a machine to do the work. That moment will be significant not just because it will signal the end of one more human niche, but because it will signal the beginning of another: the era in which it will no longer be optional for machines to have ethical systems.'"
I maintain that you CAN'T really program morality into a machine (it's hard enough to program it into a human). And I also doubt that engineers will ever really be able to overcome the numerous technical issues involved with driverless cars. But above these two problems, far and away above *all* problems with driverless cars is the real reason I think we'll never see anything more than driver *assisting* cars on the road: legal liability.
To put it bluntly, raise your hand if YOU want to be the first car manufacturer to make a car for which you are potentially liable in *every single accident that car ever gets into*, from the day it's sold until the day it's scrapped. Any takers? How much would you have to add onto the sticker price to cover the costs of going to court every single time that particular car was involved in an accident? Of defending the efficacy of your driverless system against other manufacturer's systems (and against defect, and against the word of the driver himself that he was using the system properly) in one liability case after another?
According to Forbes, the average driver is involved in an accident every 18 years. Let's suppose (and I'm sure the statisticians would object to this supposition) that that means that the average CAR is also involved in a wreck every 18 years as well. Since the average age of a car is about 11 years now, it's not unreasonable to assume that a little less than half of all cars on the road will be involved in at least one accident in their functional lifetimes. And even with the added safety of driverless systems, the first model available will still have to contend with a road mostly filled with regular, non-driverless-system cars. So let's say that a good 25% of those first models will probably end up in an accident at some point, which will make a very tempting target for lawyers going for the deep pockets of their manufacturers.
Again, what car company wouldn't take that into account when asking themselves if they want to be a pioneer in this field?
What political party do you join when you don't like Bible-thumpers *or* hippies?
The proper sequence should be:
Humans reason (with their morals) --> Humans write laws/code --> The laws/code go into the machines --> The machines execute the instructions.
Laws are not a substitute for morals; they are the output from our moral reasoning.
So if my auto-driver car had to make a choice between my safety and that of someone else, it better choose me.
