Actullay Google Glass is making a comeback and surprise it is in healthcare - also, the decisions regarding hospital software implementation is being decided at a levels above the OR surgeon. You can look at autopilot on planes (still the safest way to travel) or the auto-pilot on cars/trucks and realize that it has been proven to be a safe feature - same will apply to surgery.
This is not directed at your post but I am surprised at the number of people that don't understand what VERB is set out to accomplish - for all those that think Verb is a surgical robotics company (and if you are invested in this space) do yourselves a favor and do some research on VERB - you will be fascinated at what they are doing and it will give you a better understanding of how the Titan/JNJ/Verb pieces will fit together.
