I think, to be honest, cyber is much wider than the way we've defined it right now. The emergence of autonomous, AI-based systems leads us into areas that I think start becoming really, really crucial to understand, simply because of the fact that the decision cycles over how these systems are going to operate will impact on us.
The fact that we've started to erode the kind of silos between chemical biological warfare, nuclear warfare, conventional warfare, and hybrid warfare means that on the policy end, much more so than on the domain definition end, we have a lot of work to do.
We talked previously about military civil policy. I think that's something we somehow forgot in terms of how it relates on interstate relations over the last decade and a half, having sort of lived in the aftermath of the end of the Cold War and saying, “Well, we solved that problem with the chemical weapons treaty. We solved that problem with START and nuclear treaties.”
I think there is a lot of work to be done, not so much in terms of defining domains that may be disruptive, but simply allowing our own rule set or our own institutions—from the UN down to domestic policy, which really needs to be addressed. The impact on cyber, on chemical, and on nuclear is now starting to become entwined, and that's the challenge for us.
