- Mask cost, not etching, dominates the price of small-run test chips; lithographic masks are still made from quartz and chrome as they have been for decades, and entire dies are often discarded because their incremental cost is negligible compared to the mask set.  
- A 1991 Cypress CT9291A lithographic mask (layer 230a-apm-03-01) was mentioned as a physical artifact from the early 90-nm era, illustrating the longevity and collectability of semiconductor tooling.  
- Croquet (2004) was highlighted as an early, fully programmable “metaverse” platform—distinct from consumer VR arcade games of the late 1980s—emphasizing its role in the lineage of open, user-programmable virtual worlds.  
- Ethereum’s eight hard-forks under the Ethereum Foundation’s direction were framed as evidence of centralized governance, with the observation that a “51 % attack” on that authority paradoxically demonstrates improved ledger security while undermining the narrative value needed for ICO marketing.  
- The Third International Summit on Human Genome Editing (London, 7–9 March 2022), co-organized by the NAS, NAM, UK Royal Society, and others, was announced; participants were encouraged to contact GeneEditing@nas.edu with questions or input.  
- A Vimeo link (518734183) and an Amazon link to Arkady Martine’s novel “A Memory Called Empire” were shared, though the Vimeo content was pay-walled (“Verify to Continue”).
