That seems backwards? Robot-assisted surgery costs more and has better outcomes right now. Given how hesitant people are, these aren't going to gain a lot of traction until similar outcomes can be expected. And a rich person is going to want the better, more expensive option.

Robotic assisted surgery is only helpful in some types of operations like colon surgery, pelvic surgery, gall bladder surgery. It’s not been found helpful in things like vascular surgery, cardiac surgery, or plastic surgery.
