The life of a human being can be evaluated in terms of how many people they've interacted with, the influence they've had on those peoples' lives, and the lasting memories that people carry with them once that human has gone.

It is quite possible to apply the same metrics to "a robot" (which is actually an entire science program at JPL), and see that this program has affected the lives of many more people than most humans ever will. There are people whose entire careers have been based on this program, and the community of technicians, scientists, engineers, administrators etc around the robot is just as real as the community around any person.

If this robot ceases functioning, the entire project stops, careers are ended, and a community is fractured. To this community the robot is just as important as any human.

Your lame attempt at concern trolling shows very little respect for the community involved in this project.
