Ha I actually think the complete opposite will be true - Here in New Zealand I got a degree in neuroscience without doing any papers outside of core science, whereas in the US I would probably have to do humanities based courses etc (which I think is a fairly good thing) - and it's not unlikely that these will come to include topics in ethics.

Also ethical review boards for other areas of science are very well established, and it's not unrealistic to imagine that extending towards machine learning as well.
