- castAR’s retro-reflective projection system was critiqued for its narrow viewing cone; a proposed per-user “periscope” attachment could redirect the beam into each eye, but the one-year lead time and D&D-centric marketing were seen as drawbacks.  
- Avegant’s “Glyph” headset was debated: although marketed as a Virtual Retinal Display, it actually uses a fixed-focus DMD projector rather than true retinal scanning, making it more of a compact video viewer.  
- A newcomer seeking “low-hanging fruit” similar to nootropics was advised to master foundational disciplines—EE, CS, biotech, physics, chemistry, and sociology—as the best path toward building controlled AGI and reaching the technological singularity.  
- Participants compared brain and silicon efficiency, questioning whether neurons transmit ~1 bit per spike or richer pulse-density-encoded signals, and shared links to pulse-density modulation in biological systems.  
- Paperbot automatically delivered two open-access papers: a 2013 Genome Biology article on RNA-seq analysis pipelines and a 1993 BBA paper on protein structure, illustrating the channel’s routine use of automated literature retrieval.  
- A Kickstarter campaign for “XOWI – the world’s first personal voice companion badge” was shared, reflecting ongoing interest in wearable, voice-driven personal assistants.
