What are some of the ethical issues and concerns around AI? Ethics issues is another big question. There's certainly many capabilities in automation and in AI that are emerging that are going to lead to all abilities to track humans endlessly to identify actions and behaviors way beyond what's been possible before, and so we need to have a keen eye on what's allowed and what isn't allowed and how these technologies can be used in impact society. There are always ways to work around this, because technology fundamentally since the very beginning of human history. There have been technologies used for good purposes bad purposes. No matter how much of a good intent you put behind using something for good, it's going to be used and misconstrued in some way to be used for bad. Like fire. It's great for cooking food, but it's also great for burning people's houses down. But at the same time, you can use it to chase away the people who were burning people's houses with. So that's a good analogy for what we're doing with machine-learning. It'll be used for bad things by humans, but we will use machine learning to counter that. But it won't itself turn into this horrible thing for machines or for humans. The key point from my viewpoint is is to think of ethics in Artificial Intelligence not as something that somebody else was going to do in the future, is something when you felt like it today. So for example, today, police forces in countries like China and soon in Russia, are starting to use glasses, do image recognition, and face recognition, identify wanted person, person with warrants, for example, in a crowd and be able to better enforce law and maybe arrest a person or investigate this further. That's a technology that's in use today.
