# Key Points from #hplusroadmap IRC Discussion

• Participants discussed tDCS (transcranial direct current stimulation) technology, sharing both commercial options from Soterix Medical and DIY approaches using saline-soaked sponges on copper discs to deliver 1-2mA of current.

• A conceptual debate emerged on the distinction between biohacking and bodyhacking, with concerns about potentially harmful self-experimentation methods, particularly regarding Lepht Anonym's approach to implants.

• Technical discussions covered microfluidic valve control schemes and their layout limitations, demonstrating the channel's focus on practical engineering challenges in biotechnology.

• Participants identified specific biotech bottlenecks requiring advancement, including templateless DNA writing, high-throughput protein expression methods, and more affordable flow cytometry.

• A significant debate addressed the role of discussion versus action in transhumanism, with arguments that 30+ years of theoretical conversation has yielded less progress than focused scientific work.

• The community discussed economic approaches to advancing transhumanist goals, including proposals for an "H+ hedge fund" and an "angel circle" of technically qualified investors who could evaluate scientific business plans.

• Participants explored the potential for transhumanist cultural development through music, forums, and media, while debating whether creating new platforms fragments the community or advances the movement.
