# Key Points from Transhumanist and Technology Discussions

• Researchers discussed innovative sensory augmentation concepts, including a scheme to downconvert bat/rodent auditory frequencies to human-perceivable ranges, demonstrating ongoing interest in expanding human sensory capabilities.

• Brain imaging technologies were extensively discussed, with participants exploring nanoCT (200-400nm voxel resolution), contrast agents that cross the blood-brain barrier, and gold nanoparticles (~50nm) for non-destructive neural connectivity mapping, highlighting the frontier of high-resolution brain preservation techniques.

• The group analyzed the technical and economic aspects of medical imaging, calculating that CT scanners costing $1-3 million could generate $20-90k daily revenue, while discussing emerging technologies like electron beam tomography that offer faster scanning speeds at higher costs.

• Advanced neuroscience techniques were examined, including patch-clamp recordings during magnetic stimulation and vertical nanowire electrode arrays for intracellular interfacing with multiple neurons simultaneously, demonstrating progress in understanding neural mechanisms.

• Participants critiqued AI conceptual frameworks, with Maaku specifically challenging Minsky's concept of 'frames' as "magic boxes" that fail to specify how frames are learned and integrated into context-aware connections.

• The limitations of human cognition were discussed, with research suggesting speed-reading is ineffective beyond 600 words per minute with 75% comprehension, and that long-term memory recording bandwidth is only about half a bit per second, emphasizing the need for external cognitive augmentation.

• De-extinction technologies were debated, with participants noting the challenges of cloning extinct species like woolly mammoths through somatic cell nuclear transfer (low success rates) versus potentially more practical approaches of modifying elephant genomes with mammoth DNA.
