Give me a break! That teacher compared himself to a doctor. I never did, nor would compare myself to a doctor. You are really stretching things, don't you think? ..and by the way, just out of curiosity, who do you think programs artificial hearts? Who programs robotic medical devices? Who programs unmanned flying drones? I could go on and on. I guess software engineers probably saved many more lives than you can possibly think of. Nevertheless, that wasn't my point, and you know it.
