As an earlier poster said, it is nothing to do with &quot;trust&quot;. Software has bugs, surgeons make mistakes. What matters is the relative degree of statistical risk.<p>If the risk of falling victim to a bug&#x2F;mistake by a software surgeon is lower than that of a human surgeon, then simple desire for self-preservation you should choose the software. To choose the human over the software, even when it&#x27;s provably more dangerous is allowing a baseless prejudice to put you at higher risk. It&#x27;s equivalent to being given the choice between two human surgeons of differing skill levels, and choosing the lesser skilled surgeon on the basis of their ethnicity.
