Not necessarily-in East Asian cultures as you well know ,Chinese,Japanese,Korean and Vietnamese-one can never study too hard or be diligent enough in studies or work .a good trait actually ....if not taken to harmful extremes/or used as a way to reject or condemn wrongly.Bad examples:suicides of students or dying at work.Not sure if a good idea. According to the article, "the AI has no psychological or physiological limit of human pilot, forcing pilots to give everything they have got..." That don't sound like a good practice. Being more difficult is not better, if it is not realistic. It could even breed bad habits.
