- Josiah Zayner and Aaron Traywick are embroiled in a lawsuit (linked Facebook post) that is technically directed at Gizmodo, highlighting ongoing legal tensions in the biohacker community.  
- A proposal floated that $500 M could fund a 5-year push to reach 4–5 nm feature sizes for cryptocurrency-mining ASICs; participants debate whether this figure is realistic given that a full 5 nm fab is estimated at ~$14 B.  
- Alternative nanolithography routes discussed: DNA-origami or protein-based masks for partial self-assembly, direct e-beam lithography, and skepticism that conventional EUV scaling assumptions are accurate.  
- Brain–computer interface concept: use magnetically steerable glia or other cells as “programming agents” that traverse brain tissue and set synaptic weights, possibly via a JTAG-like white-matter bus, enabling copying of connectomes from plastinated brains into living tissue.  
- Concern raised that stochastic wiring (“pseudorandomness of synaptic connections”) may block one-to-one connectome transfer; echo-state networks cited as an example where only input/output layers are trained, leaving hidden layers non-transferable.  
- Synthetic-neuron idea: design protocells that exhibit neuronal electrophysiology but lack evolutionary “cruft,” then self-assemble them into small, globally coherent circuits—though participants note self-assembly alone struggles to deliver large-scale, precise interconnects.  
- Link shared to TowerJazz specialty-process technology page as a resource for non-leading-edge but accessible fab options.
