# Key Points from ##hplusroadmap IRC Discussion

• Participants shared advancements in brain-computer interface technology, specifically a transcranial Doppler ultrasonographic system for controlling an onscreen keyboard, representing ongoing progress in non-invasive BCI methods.

• Extensive digital library resources were highlighted at http://diyhpl.us/wiki and http://diyhpl.us/~bryan/papers2/, containing collections on biohacking, longevity, neuroscience, and DIY biology, serving as a knowledge repository for the transhumanist community.

• The conversation revealed tension between newcomers seeking structured introductions to transhumanism and experienced members advocating for self-directed learning through wiki resources, highlighting challenges in knowledge transfer within the community.

• Participants discussed tissue engineering advances with bone marrow-on-a-chip technology that replicates hematopoietic niche physiology in vitro, demonstrating progress in creating biological systems outside the body.

• The group critiqued regulatory barriers preventing access to beneficial technologies like the iBot mobility system (advanced wheelchair), while expressing frustration that transhumanist organizations focus on ethics rather than developing practical technologies.

• Technical discussions included cryptocurrency mining algorithms, with debates about whether ASIC-resistant designs lead to more or less centralization, and the limitations of blockchain technology for authenticating physical assets.

• DIY technology projects were discussed, including homemade semiconductor fabrication, metal deposition print heads for 3D printing, and the potential for building low-cost NMR (Nuclear Magnetic Resonance) equipment with tradeoffs between measurement time, electronics sensitivity, and magnet strength.
