I'm using the simple definition that murder is killing with intent, barring modifiers such as a state of war or emotional modifiers, which machines are incapable of.

Computer systems are deterministic - if we give it A, we expect to get B, not C or D in some unpredictable pattern. If we do somehow get C, that is an error, not an insight. If we allow that the machine is correct 90% of the time, it's still in error but furthermore we have now codified an acceptable error rate. A human or group of humans had to make that decision, because computers are incapable of deciding what is acceptable or not acceptable.

Ergo, when you step off the curb into the path of that self-driving car, someone has already made a decision that 10% of the time, you die. The stated intent might be to maximise the preservation of the lives of the vehicle's occupants or that group of schoolchildren or a dog or whatever, but the unstated intent is that someone has to die.

Which means it is codified killing, or murder. It is not a happy (or unhappy) accident of the universe.

By this logic doctors are murderers whenever they perform an operation and the patient dies, all equipment manufacturers that make something that's ever resulted in a death are murderers, all engineers of bridges that collapse under extreme conditions are murderers.

Really widens the net for the concept of murder.

If they ever formally codified the acceptable risk resulting in death and operated accordingly, then yes, they might be.

However, a doctor is not a machine - there isn't some piece of code that says 10% of all appendicitis cases die. Equipment deaths are usually operator error or perhaps component failure, etc. Bridges? Who knows?

The point is that an autonomous vehicle has a programmed decision tree where the others do not and at some point, someone has to have, or should have, taken into account vehicle operation under catastrophic circumstances.

Go read up on the trolley problem and tell me if I'm wrong in bringing this up.
