1. It isn't surprising to me that this happened in an advanced AI model. It seems hard to avoid in, as you say, "any sufficiently capable system".

2. It is a bit surprising to me that it happened in Claude. Without this result, I was unsure if current models had the situational awareness and non-myopia to reason about their training process.

3. There are some people who are unconcerned about the results of building vastly more powerful systems than current systems (i.e. AGI/ASI) who may be surprised by this result, since one reason people may be unconcerned is they feel like there's a general presumption that an AI will be good if we train it to be good.
