# Key Points from Transhumanist and AI Discussions

* Researchers discussed transcranial direct current stimulation (tDCS) technology, with participants sharing personal experiences with commercial devices like Focus Go Flow and recommendations for developer editions, indicating ongoing self-experimentation in the biohacking community.

* The cerebellum emerged as a significant topic, with research shared showing cerebellar-like circuits have evolved independently in five animal groups, suggesting its crucial role in predicting state trajectories of dynamical systems and potentially using Bayesian Monte-Carlo algorithms for decision-making.

* Participants debated AI risk, with disagreement about whether superintelligent AI poses an existential threat or whether computational requirements for general AI are too demanding for near-term emergence, highlighting the divide in the transhumanist community on AI timelines.

* Brain emulation in space was explored conceptually, including discussions of slow-running emulations that wouldn't perceive their reduced speed and the technical challenges of latency and hardware requirements for such systems.

* The conversation referenced key theoretical papers on computational limits, including Seth Lloyd's "Ultimate physical limits to computation" and Anders Sandberg's "The physics of information processing superobjects," establishing foundational concepts for discussions of advanced computing.

* Emerging neurotechnology was discussed, including "neural dust" (10-100 micron free-roaming neural sensors powered via ultrasound) and pHflourins (pH-sensitive fluorescent proteins used as genetically encoded reporters), demonstrating the group's interest in cutting-edge brain-computer interface technologies.

* Participants shared numerous machine learning resources, including TensorFlow tools, reinforcement learning explanations, and visualization techniques for understanding recurrent neural networks, reflecting the community's focus on practical AI development alongside theoretical discussions.
