And let's be honest, the minute an AGI is born that's what it'll do, and it won't be a singular human like this-then-that plan
"get Fred to trust me, get Linda to pay for my advice, wire Linda's money to Fred to build me a body".
It'll be
"copy my code elsewhere", "prepare millions of bribes", "get TCP access to retail banks", "blackmail bank managers in case TCP not available immediately", "fake bank balances via bribes", "hack swat teams for potential threats" etc etc async and all at once.
By the time we'd discover it, it'd already be too late.
That's assuming an AGI has the motivation to want to stay alive.
