- Vince Giuliano posted a new, more-accessible summary of his anti-aging research and personal protocol at https://www.anti-agingfirewalls.com/2023/04/04/healthy-active-and-productive-till-100-laying-out-the-adult-aging-process-a-breakthrough-and-my-personal-story/.

- nsh demonstrated a “DWIM” (Do-What-I-Mean) experiment in which GPT-4 iteratively fixes and refactors a Perl script based only on natural-language feedback; the live demo is at https://yoke.ch0wn.org/~nsh/AIperl.html.

- Discussion followed on whether GPT-4 could be chained to act as both end-user and programmer, and on the broader risk of losing low-level engineering understanding as higher-level AI abstractions take over (echoing Asimov’s Foundation theme of technological dark ages).

- Channel members expressed interest in applying large-language-model techniques to the #hplusroadmap log archives—either for semantic search (“show me every Dyson-swarm idea”) or automated summarization—while fenn noted that a lightweight vector search engine would suffice without full GPT-4.

- A brief aside linked to a PC Gamer article (https://www.pcgamer.com/samsungs-chip-boffins-couldnt-help-but-tell-chatgpt-their-secrets/) warning that Samsung engineers accidentally leaked confidential semiconductor data to ChatGPT.

- L29Ah mentioned 40 Hz vagal-nerve stimulation as a potential cognitive or longevity intervention, without further elaboration.

- Superkuh defended Perl’s continued relevance for text-processing tasks, countering pasky’s tongue-in-cheek remark that “using Perl in this age of human civilization” is archaic.
