For that purpose, any cyber operator worth their salt will tell you true physical airgaps are more than merely "realistic"; they are categorically necessary.
Cyber operators I agree would tell you that physical airgaps are necessary, and I know they are being used for running agents. But ML engineers training agents? That is far more complicated. At that point sensibly you are talking about physically airgapping an entire datacenter, and when moving around petabytes of training data, model weights, training results, researcher code? The process moves too slow for most companies to tolerate. This is how we got into this mess in the first place. I think the industry woke up to the idea that the security threat model of training ML models has fundamentally been rewritten, and there is some serious non-trivial scrambling to come up with a better workflow.
