- Debated whether nanofactory DRM or centralized control could prevent malicious “malbots,” concluding that once nanofactories can mine sunlight and air, resource scarcity—and thus control—becomes meaningless.  
- Calculated that a 100 mg self-replicating nanofactory with a 2-week doubling time could convert Earth’s entire 6 × 10²² kg crust into products in ~41 months, and Jupiter’s 1 × 10²⁷ kg mass in ~48 months, making planetary-scale resource grabs a realistic scenario.  
- Argued that even if atmospheric carbon, nitrogen, and oxygen become abundant, scarce elements (e.g., argon, boron) and the Earth’s crust itself will remain geopolitical bargaining chips because strip-mining the crust destroys the biosphere.  
- Discussed extreme geo-engineering futures: compressing or cryo-freezing the atmosphere to create frozen wastelands, then selling the captured air to survivors in habitat domes as a form of economic leverage.  
- Noted that fusion and stellar mining of the Sun face the hurdles of extreme gravity, the “on-fire” state of solar material, and the side-effect of extinguishing sunlight for the rest of the solar system.  
- Shared Newsweek article on 11-year-old Laurent Simons, who aims to “make humans immortal,” prompting skepticism that mastering quantum physics is the wrong path to that goal.  
- Posted GPT-3-generated dialogues simulating Eliezer Yudkowsky abandoning long-term AI-risk goals and urging followers to pursue more practical projects, illustrating a critique of the effective-altruism/x-risk community.
