- Space-mined asteroid gold was discussed as a potential market disruptor; participants debated whether early missions could realistically deliver enough tonnage to crash terrestrial gold prices (global 2019 production ≈ 3,300 t).  
- Technical ideas for safely de-orbiting multi-ton gold payloads included casting the metal into aerodynamically stable “nose-first” shapes, using heat-shielded frames, and employing vernier thrusters or “reverse coil-gun” decelerators to avoid cratering.  
- Skyhooks—spinning orbital tethers that exchange momentum between upward and downward payloads—were proposed as a reusable, low-energy alternative to rockets for both lifting mass to orbit and landing heavy asteroid material on Earth; the main challenge cited was economic bootstrapping.  
- Broader implications of ultra-cheap gold were noted: more energy-efficient electronics, gold power cables, and the “supervillain” scenario of deliberately fragmenting incoming asteroids to preserve scarcity.  
- A Discover Magazine article on in-vitro gametogenesis from bone marrow was shared, prompting a tongue-in-cheek reversal: “how close are we to making bone marrow from babies?”  
- The diyhpluswiki repository was updated with transcripts of Kalle Alm’s February 2020 Signet workshop from the Advancing Bitcoin conference, expanding open-source documentation on Bitcoin testing infrastructure.
