- Discussion of a blog post arguing that personal identity cannot split or merge, contrasted with Derek Parfit’s “Reasons and Persons,” which treats identity as potentially divisible and non-continuous; participants noted the post’s unsupported conclusions and its similarity to philosophical-zombie arguments.  
- Parfit’s teletransporter thought experiment and the Ship of Theseus problem were invoked as canonical treatments of continuity-of-identity questions already familiar from introductory philosophy courses.  
- Practical stance voiced by several members: once the philosophical landscape is mapped (e.g., by Parfit), further armchair speculation is less valuable than “just build things,” reflecting the channel’s engineering bias.  
- Harry Frankfurt’s essay collection “The Importance of What We Care About” was linked (archive.org) as additional reading on agency and identity.  
- A Science paper (Science 215:1534, 1982) on behaviorally conditioned immunosuppression in mice was shared, highlighting psychoneuroimmunology as a route to non-pharmacological modulation of immune responses.  
- Deep hypothermic circulatory arrest (DHCA) was highlighted as a clinically validated method for inducing complete, reversible brain inactivation via cooling to 20–25 °C, relevant to cryonics and suspended-animation research.  
- New EU import regulations effective 1 Jan 2021 were flagged as likely to complicate ordering electronic components from outside Europe; RoHS was cited as an example of prior regulation that successfully reshaped supply chains.
