Doom argument without ASI or misalignment

First post. I have a Doom argument I’m not sure I’ve seen before. End conclusion at bottom is most of humanity dead but note the following about the premises listed below:

  • No ASI required

  • No misalignment scenario of AI with its creators required

  • No genocidal desires required by anyone

Premises

P1. Global power of a nation comes from military strength and international trade.

P2. Military strength and trade require labour and resources.

P3. Genociding your own population reduces available human labour.

P4. The majority of capital and supply chains are currently geared towards producing goods and services for human populations (food, clothing, housing, entertainment, healthcare, …).

P5. (AGI) Most human labour will be automated by AI.

P6. Resources currently devoted to sustaining a human population can be redirected to military and industrial production and trade exports.

P7. Nations compete for global power, and a many fold advantage in military and trade strength allows a nation to dominate or overrun those without it.

Backward looking conclusions

C1. From P1 + P2: Global power requires labour.

C2. From C1: Capital and supply chains geared towards producing goods and services for human populations are currently a positive return on investment for national leaders.

C3. From C1 + P3: Historically, genociding your own population has always reduced your global power and is a negative return on investment in terms of global power.

Forward looking conclusions

C4. From C1 + P5: Once labour is automated, global power no longer requires a human population.

C5. From C2 + C4: Capital and supply chains geared towards sustaining a human population will cease to be a positive return on investment in terms of global power.

C6. From C3 + C4: Genociding your own population will no longer reduce global power.

C7. From C5 + P6: Genociding your own population and redirecting those resources to military and industrial production increases global power.

C8. From P4 + C7: Because the majority of capital and supply chains currently serve human populations, that increase is many-fold rather than marginal.

C9. From C6 + C7 + C8: Genociding your own population becomes the rational move for maximising global power.

C10. From C9 + C8 + P7: A nation that refrains cannot compete—it is dominated or overrun by one that did not refrain.

C11. From C9 + C10: A pre-emption game begins. It requires only one nation to act first, after which every other nation must either follow or be overrun.

C12. From C11: A coalition of refrainer nations has to act against the first mover pre-emptively on a forecast, against a nuclear power, which is unlikely.

C13. From C11 + C12: Globally, nation states will have to either eliminate their human populations or be overrun by those that do.

C14. From C13: Humanity will largely be eliminated.
