Again, why? You're here posting your thoughts to impressionable young (and not so young) students like me.
Because it's a very important proof of concept.
Also, in time, these tools will get advanced enough that they can be used by anybody able to program them, not just surgeons, who will be the backup plan. They might sell them in the beginning as intelligent tools for surgeons but, in time, they will be used by PAs, while surgeons will supervise multiple rooms as firefighters. Of course, there will be other intelligent tools for other procedures; the more intelligent the tools are, the less they will need a surgeon's talent and experience. They will mostly need just programming, positioning and supervision.
By the time we or our kids die, medicine might belong to nurses and techs, using intelligent tools for diagnosis and treatment. Already, an APRN plus Dr. Smartphone can be enough for a number of pathologies. And Dr. Smartphone is still just an information repository now, not an intelligent tool.
You probably don't remember when only doctors used stethoscopes and read EKGs.
The only thing that slows down technological progress in American medicine significantly is lack of malpractice reform.
