Yes, the meta ethics are interesting, but the idea that this is any more actionable than trolley problems is silly.

the point is, that we are reaching the point where trolley problem stops being “interesting theoretical brain teaser” and starts being something to which we have to know the answer.

because we have to know, as in we have to decide, whether we have to flip the switch or not. we have to decide whether we are going to protect these three over that one one. whether this kid has more right to live than the senior, because the senior’s life is almost over anyway. whether that doctor’s life is more valuable than grocery clerk’s one.

and so on.

up until now, there wasn’t really a decision. majority of people have problem controlling the car under normal circumstances, in case of accident, they just hit a break, close their eyes and pray. whatever happens is really just result of chance, there isn’t much philosophy about value of life in play.

there is still some reasoning though, most of us probably won’t steer the car to a group of kindergarten kids on the sidewalk just to protect themselves.

but the car will have more and will be able to evaluate more information than a person can in such short time and the car will be able to react better.

the only thing that remains is, we have to tell him what to do. we have to tell him whose life has bigger value and whose life is worth protecting more. and that is where the trolley problem stop being academic exercise.
