Experienced professionals need continued education and training. A surgeon meeting such requirements can read manuals, watch videos of surgery procedures, and listen to podcasts. However, none of these will give the surgeon a true feeling of the operating room. This also applies to other hazardous professions like fighter pilots, electrical linemen, and so on. These professions, in particular, need to train under realistic conditions in order to perform well at their job. Virtual reality solves this problem to a great extent.
