- The channel revisited Nancy Kress’s 1993 novel “Beggars in Spain,” which imagines a society where genetically engineered “Sleepless” humans need no sleep and outperform baseline humans, framing the ethical question of what productive citizens owe to the unproductive masses.  
- Discussion linked the novel’s premise to real-world research on “familial natural short sleep,” a rare genetic trait that allows individuals to sleep far less than average without impairment, suggesting near-term feasibility of similar enhancements.  
- Participants warned that AI-driven automation is poised to trigger “an AI-assisted mass disruption in employment,” echoing the book’s social tensions between enhanced and unenhanced populations.  
- A 2009 Austin scifi lunch and H+ Summit session were recalled as early venues where these themes circulated, with Joan Slonczewski’s “The Brain Plague” noted as a related text on genetic and societal consequences.  
- The conversation emphasized the need for transparent, publicly documented jargon (“tafting”) to prevent insular communities from losing shared meaning, referencing the xkcd comic on Wikipedia rabbit holes.  
- A new pre-print (bioRxiv 2022.11.07.515423) was shared, arguing that age-related changes in cortical 1/f neural dynamics are largely explained by cardiac activity rather than intrinsic brain aging, with potential implications for brain–computer interface signal processing and gerontechnology.
