- A YouTube video titled “WHATEVER HAPPENED TO GRAPHENE? (UPDATE)” was shared, prompting reflection on the gap between graphene hype and real-world deployment.  
- Participants lamented the decade-long wait for promised memristor-based computers, noting that the technology was heavily touted around 2008 yet remains commercially absent.  
- Discussion turned to the ethics and practicality of extracting DNA from historical envelopes: links to a Reddit thread (gwern’s comment) and a BBC article about purchasing Einstein letters (~US$6 k) were provided, along with an auction lot containing correspondence from Schrödinger, von Neumann, Szent-Györgyi, and Wiener.  
- Concerns were voiced about the reliability of recovering usable DNA from aged, possibly wax-sealed envelopes and the financial risk of paying thousands for letters that might yield no genetic material.  
- A brief tangent explored the physical limitations of paper—specifically, its inability to stretch—when attempting to create a Möbius strip for algorithmic visualization.  
- The Carboncopies RSVP page (https://carboncopies.org/rsvp/) was circulated, likely related to upcoming whole-brain emulation or mind-uploading events.  
- Hayabusa2’s asteroid touchdown and sample-return explosion footage was highlighted as a milestone in robotic space resource retrieval.  
- A full-day archive of the bitcoin-dev mailing list (March 5, 2019) was mirrored at diyhpl.us, with a pointer to a specific message on the list for technical review.
