- A debate on human height modification highlighted practical downsides: taller bodies require rebuilding infrastructure (clothing, transport, ceilings, door frames) and raise metabolic cost questions, while one participant argued for shrinking humans to <1 ft to gain resource and space efficiencies.  
- JayDugger referenced Robin Hanson’s 1994 essay “If Uploads Come First,” specifically the section suggesting fast uploads might choose proportionally smaller physical bodies to match accelerated cognition.

- Nvidia’s AI-driven high-resolution face-generation research was shared via two YouTube links: a technical talk by Tero Karras and a one-hour “imaginary celebrities” screensaver of GAN-produced faces.  
- The channel noted the arrest of a U.S. bitcoin trader for “unlicensed money transmission,” prompting review of earlier cases like Charlie Shrem and discussion of regulatory requirements for international money transfer.  
- Technical resources mentioned: RFC 8391 (XMSS hash-based digital signature scheme), Amber molecular-dynamics tutorials, and the HECBioSim simulation-software download page.
