Micheal Simmons Posted about 2 years ago Is an engineer morally responsible for harm caused by their creations? Many books and articles argue this point endlessly. Hindsight is indeed 20/20. When the Manhattan project was begun the biggest fear was that Nazi Germany would develop and use an atomic bomb first. There is some anecdotal evidence that Heisenberg was able to subtly sabotage the project to prevent its fruition. Norway's shipments of heavy water south were known. The Japanese effort was not nearly as far along. Oppenheimer wanted the post war world to have ready access, so as to eliminate any "arms race" that would ultimately develop if one nation had the "secret" and the others wanted that same secret. Be that as it may, unfortunately most of the world's most prominent advances is technology, science and medicine are usually linked to major conflicts. Reconstructive surgery is a premier example in the field of medicine. Also be aware that no matter what the engineer's intent in his/her creation is, it can always be modified by others to make an extremely efficient weapon to some degree. Maxim invented the machine gun hoping that such a horrible weapon would reduce the number of conflicts that would require its use. He did not succeed.
