Yes you are quite right - it takes time to gain proficiency in any skill, even in laproscopic surgery, perhaps especially laproscopic. Robotic surgery is no different in this respect.
This learning curve scare is just the latest tactic of the nay sayers. It looks very damaging at first sight but is no more important than the learning curve of laproscopic - perhaps is not even as difficult as robotics is intuitive not counter intuitive like laproscopic.
It might frieghten off some less well informed patients, but I guess not the professional surgeons or intellegent patients. And the truth will surface very quickly. The frauds like Dr Hu will be shown up what they are.
There is no more disreputable half truth than the totally flawed report from Dr Hu who seems to have his own agenda. Is it possible that he was rejected form a robotics training course- just a thought.
This week looks like the last stand of the nay sayers.
