Two different questions get filed under this heading, and confusing them is why so many AI risk exercises stall.
The first is risk from the AI you have adopted: the tools your teams use, what they do with your data, whether their output can be trusted. That is a real and bounded question, and frameworks like the NIST AI Risk Management Framework exist to answer it.
The second is risk from AI in the world, whether or not you have adopted anything: your competitors moving faster, fraud against you becoming cheaper to run, your suppliers automating decisions that affect you, your customers arriving with new expectations. This is the larger of the two, it is the one most registers miss, and it is what this hub is about.
Put plainly: AI is not a new line on your risk register. It is changing the lines already there.
