Dilemme du tramway

[Purosangue]

Et si le conducteur du tramway et celui qui aiguillonne le rail étaient des LOGICIELS ? Comment seraient-ils programmés ? Et si le dude derrière l'obèse étaient un robot. Serait-il capable d'appliquer les trois lois de la robotique ?

La version médicale donne froid dans le dos:

A brilliant transplant surgeon has five patients, each in need of a different organ, each of whom will die without that organ. Unfortunately, there are no organs available to perform any of these five transplant operations. A healthy young traveler, just passing through the city the doctor works in, comes in for a routine checkup. In the course of doing the checkup, the doctor discovers that his organs are compatible with all five of his dying patients. Suppose further that if the young man were to disappear, no one would suspect the doctor.
