- A participant proposed an optically-controlled switch using a cracked glass slab whose total-internal-reflection could be toggled between near-perfect transmission and complete reflection via a strong light-frequency electric field exploiting the nonlinear Kerr effect near the critical angle.

- Whole-brain emulation feasibility was discussed, referencing Eugene Izhikevich’s 2005 simulation of 100 billion neurons (one second took 50 days on a 27-processor cluster) and the estimated 10 petabytes of RAM required to store all synaptic weights.

- Hardware scaling estimates suggested ~136,500 NVIDIA Titan Black GPUs (≈52 MW) or ~405,000 GTX 750 Ti GPUs (≈24 MW) would be needed for real-time human-brain-scale simulation, illustrating current power and cost barriers.

- DARPA’s FY2015 budget request and BTO program list were highlighted as sources of upcoming neuromorphic-processor and memory-centric research funding.

- Historical transhumanist content was shared, including full transcripts of the 2009 Singularity Summit (Sandberg, Boyden, Salamon) and the 2009 H+ Summit (Levskaya, Lightman, Morris, Fahy, Benford, Huffman).

- The channel explored whether elliptic-curve cryptography can be performed securely “in your head,” concluding 160-bit keys (≈48 decimal digits) are the minimum for real security, with hand multiplication of 70–80-digit numbers as the practical bottleneck.

- Participants discussed mnemonic and base-encoding tricks (base-16, base-100 digit pairs, story-based word substitutions) to shrink key sizes or ease mental computation, while noting eye-tracking or written crib sheets could leak entropy.

- A 2014 Nature Neuroscience paper on “Implication of sperm RNAs in transgenerational inheritance of the effects of early trauma in mice” was linked, highlighting emerging evidence for epigenetic memory transfer.

- Discussion of transcranial direct-current stimulation (tDCS) included safety references (a 2007 ScienceDirect review) and practical questions about electrode gel and consumer devices like “thebrainstimulator,” with the Algernon argument (Gwern’s drug-heuristics essay) raised as a caution against cognitive enhancement hype.

- Sci-fi with transhumanist themes came up, including Hannu Rajaniemi’s “Quantum Thief” series (post-singularity, dense style) and comparisons to Gene Wolfe and David Zindell, alongside sharing of personal writing and market-analysis work on “DaaS” (database-as-a-service).
