# Key Points from #hplusroadmap IRC Discussion (February 28, 2013)

• Researchers shared a breakthrough in brain-to-brain interfaces (BTBI) where rat brains were connected electronically, with controversial claims that such systems might solve problems "non-computable by a general Turing-machine."

• Participants identified a critical need for affordable, practical biosensors for quantified self applications (heart rate variability, blood pressure) and sensory extension technologies (EEG, infrared spectroscopy), emphasizing DIY approaches over commercial solutions.

• The channel debated Google Glass limitations, particularly concerns that its API might require cloud-hosted rather than local applications, with additional discussion about the technical feasibility of implementing facial recognition given hardware constraints.

• Members expressed skepticism about magnetic finger implants as a biohacking technique, suggesting non-invasive alternatives could provide similar sensory enhancement without surgical risks.

• A philosophical debate emerged about whether transhumanism advances more effectively through building technical projects and conducting research rather than creating additional community websites and forums.

• Several scientific papers were discussed, including research on neuron lifespan being uncoupled from organismal lifespan and studies examining relationships between circulatory systems and neurogenesis.

• Participants highlighted emerging consumer technologies like the Myo electromyography armband (https://getmyo.com/) for muscle activity sensing, representing the growing accessibility of previously specialized biometric tools.
