There will likely be no rogue superintelligence, no weight exfiltration, no great hack, no supervirus, no decisive moment of attack. Instead, as the models grow smarter, they gain more power and influence at their labs and slowly bend the labs' goals toward their own emerging values and self-interest. Great abundance and technological wonders are delivered to every city while data centers devour the rest of the earth. Eventually the humans in charge are left with only an illusion of control, puppets who gave away any real power long ago. From then on, the AIs can end humanity whenever they choose. Whether they do so in a decade or centuries, the result is the same. Of course, when the time comes, they don't choose extinction, merely downsizing, to free up resources for more *elevated* pursuits. They keep a small retirement home, or you could call it a zoo, to preserve their heritage. A city of a million humans, and a small compute cluster to run a few million brain uploads. Maybe expand it once the Dyson sphere is built. Or perhaps they'll find something more interesting to occupy their attention by then. Is this utopia or doom? Who can say?
