- Discussion of combining GloVe or Word2Vec word-embeddings with unsupervised clustering of vector differentials to automatically build a semantic knowledge base, plus the idea of integrating attention-weighting for contextual inference.  
- Reference to Stanford’s 2013 paper “Reasoning With Neural Tensor Networks for Knowledge Base Completion” (Socher et al.) as a concrete example of learning relational tensors over word embeddings.  
- Mention of an electrochemistry + CMOS + Twist Bioscience approach to DNA synthesis, with kanzure noting he had forgotten the technical details.  
- Link to a 2007 paper on “Self-deployed extremely large low-mass space structures” (diyhpl.us/~bryan/papers2/space/…) as background for building kilometer-scale star shades.  
- Brief exchange about a real US–Italian tether experiment where a 20 km shuttle-to-probe tether broke, illustrating prior work on very long space tethers.  
- Debate over Elon Musk’s appeal to the United Nations for a ban on lethal autonomous weapons; concern that such regulation could drive AI research underground and increase secrecy.
