Won’t 8 billion people will have incentive to move to Samoa in that case?

Realistically, in an AI extreme economic disruption scenario, it's more or less USA the only one extremely affected, and that's 400 million people. Assuming it's AI and nothing else causes a big disruption before, and with the big caveat that nobody can't predict the future, I would say:

- Mexico and down are more into informal economies, and they generally lag behind developed economies by decades. Same applies to Africa and big parts of Asia. As such, by the time things get really dire in USA and maybe in Europe and China, the south will be still in business-as-usual.

- Europe has lots of parliaments and already has legislation that takes AI into account. Still, there's a chance those bodies will fail to moderate the impact of AI in the economy and violent corrections will be needed, but people in Europe have long traditions and long memories...They'll find a way.

- China is governed by the communist party, and Russia have their king. It's hard to predict how will those align with AI, but that alignment more or less will be the deciding factor there, and not free capitalism.
