In Canada we have a legal responsibility as engineers for the people that use our designs, but do we have an ethical responsibility as well? This week we ask a lot of questions, but arrive at very few answers. Prompted by an episode of Radiolab, we discuss the moral and ethical implications of R&D. If any platform can be misused, at what point do you shut it down? And whose job is it to make that decision? If there is one thing we can all agree on, it is that engineers need to think more.
