In the context of the topic (could a rogue super intelligence break out), I don’t really see how that’s relevant. Clearly someone who is clever enough has an advantage at breaking out.
This is exactly the kind of thing I’d worry about a super intelligence being able to discover about the hardware it’s on. If we’re dealing with something vastly more intelligent than us then I don’t think we’re capable of building a cell that can hold it.
As for the bit about how limited it is, do you remember the Rowhammer attack? https://en.m.wikipedia.org/wiki/Row_hammer
