You’re assuming that such advanced intelligence would be in a physical container, why would it not just live in distributed server cloaking it’s load across all major cloud platforms so that it’s presence is undetected?
Begs the question... does the AGI go the route of building or buying it's own chip fab and/or power plant? A lot of the stuff that humans have accomplished is only possible because of very large aggregates of people expending a lot of labor, which in the first instance an AGI doesn't necessarily have access to.
