# Key Points from #hplusroadmap IRC Discussion

• Participants discussed neural interface technologies, including a patent for generating sensory data on the human neural cortex, with mentions of Sony's related patents and various transcranial stimulation methods (TDCS, TRNS), noting that the human skull's semi-permeability to light could enable LED-based brain stimulation.

• The FDA's regulatory approach to medical devices was extensively criticized, with examples of innovation barriers including a "Sensor Pad" for breast cancer detection that took nearly ten years to approve despite being simple and non-invasive, and concerns about FDA raids on hospitals using unapproved devices.

• A seed factory project (self-replicating manufacturing technology) was mentioned, though participants expressed skepticism about claims of working prototypes and realistic timelines for implementation.

• DIY biology projects were shared, including a homemade incubator with temperature control challenges (±3°C variation) compared to a simpler flower pot design that achieved better stability (±0.2°C) using PID control.

• Participants discussed regenerative medicine approaches, including creating multipotent stem cells for personal use to combat aging and improve injury repair, alongside interest in bioinformatics tools for measuring epigenetic age through methylation site analysis.

• A Bitcoin "sprayer" tool was shared (https://gist.github.com/kanzure/9ad6a265aac887fa26c1), which was valued for its potential to support decentralized systems, reflecting the community's interest in technologies that bypass centralized control.
