Thank you.
I share your enthusiasm for identifying challenges in a sector that is so unknown to us. This is Quantum-Safe Canada's area of expertise, so I'm going to tell you what I think, and you can correct me if I'm wrong.
You consider the threat to be very serious, and it is clear that Canada is at the back of#s the pack as far as its ability to defend against outside threats is concerned. The threat is not exaggerated per se, but is certainly more serious than people in general realize.
The solutions you are proposing focus on mechanics, techniques and technology. Given your extensive expertise, we can assume those solutions address the problem that lies before us. I don't necessarily think the threat has been exaggerated, but I do think the level of confidence in the proposed solutions is very high. The more, however, we talk about the technical dimension, the less we consider one specific element. I'm talking about the only risk you have no control over: the human element. No one has been able to come up with a satisfactory solution to that problem thus far.
Even if you have the best, most ironclad system in the world, the unpredictability of the human element makes it impossible to control the situation. The system can fall apart like a house of cards, because of the psychological element, or social engineering. I don't think, though, that AI is the way to manage the human risk. I'd like to hear your thoughts on that.
