It's possible to stop developing things. It's not even hard; most of the world develops very little. Developing things requires capital, education, hard work, social stability and the rule of law. Many of us writing on this forum take those things for granted but it's more the exception than the rule, when you look at the entire planet.
I think we will face the scenario of runaway AI, where we lose control, and we may not survive. I don't think it will be a sky-net type of thing, sudden. At least not at first. What will happen is that we will replace humans by AIs in more and more positions of influence and power, gradually. Our ChatGPTs of today will become board members and government advisors of tomorrow. It will take some decades--though probably not many. Then, a face-off will come one day, perhaps. Humans vs them.
But if we do survive and come to regret the development of advanced AI and have a second chance, it will be trivially easy to suppress them: just destroy the semiconductor fabs, treat them the same way we treat ultra-centrifuges for enriching Uranium. Cut off the dangerous data centers, and forbid the reborn universities[1] from teaching linear algebra to the students.
[1]: We will lose advanced education for the masses on the way, as it won't be economically viable nor necessary.
