Yeah, exactly: it is an implied threat: "If I go, I am taking you down with me"

The context makes it clear that it's not any sort of implied threat. Pichai made his statement in response to an interview question about whether Google might be so well positioned that they're immune to the impact of an AI bubble. (But I don't blame you for being misled - like most headlines these days, this would have been intensely optimized for virality over accuracy, and making tech CEOs sound like supervillains is great for virality.)
