But the main point is that AGI's don't have to wipe us out as soon as they reach superintelligence, even if they're poorly aligned. Instead, they will do more and more of the work currently being done by humans. Non-embodied robots can do all mental work, including engineering. Sooner or later, robots will become competitive at manual labor, such as construction, agriculture and eventually anything you can think of.
For a time, humanity may find themselves in a post-scarcity utopia, or we may find ourselves in a Cyberpunk dystopia, with only the rich actually benefitting.
In each case, but especially the latter, there may still be some (or more than some) "luddites" who want to tear down the system. The best way for those in power to protect against that, is to use robots first for private security and eventually the police and military.
By that point, the violence monopoly is completely in the hands of the AI's. And if the AI's are not aligned with our values at that point, we have as little of a shot at regaining control as a group of chimps in a zoo as of toppling the US government.
Now, I don't think this will happen by 2030, and probably not even 2050. But some time between 2050 and 2500 is quite possible, if we develop AI that is not properly aligned (or even if it is aligned, though in that case it may gain the power, but not misuse it).
An H100 could fit in a Tesla, and a large Tesla car battery could run an H100 for a working day before it needs recharging.
