Tacit knowlede and domain expertise in a world of LLMs

AI summary

LLMs require tacit knowledge and domain expertise to produce useful results, as domain experts can verify correctness even if they can't code, while generalist engineers can build but lack the "ground truth" to judge domain-specific outputs. The binding constraint has shifted from building to verifying what is correct.

On "mattering" in a philosophical sense

AI summary

Rebecca Newberger Goldstein defines mattering as being deserving of attention, particularly self-attention, which makes humans normative, value-seeking creatures. She proposes four empirical categories of "mattering projects": socializers, transcenders, heroic strivers, and competitive matterers. Goldstein closes with the normative claim that the very desire to matter demonstrates that we already do, so any project based on denying others' worth is mistaken.

AI ventriloquism

AI summary

A manager used an AI assistant to mediate workplace communication, forcing the author to front-run his own comments to avoid being misrepresented by the AI.

Quotations from 'How to Do Nothing'

AI summary

The note collects highlights from Jenny Odell's "How to Do Nothing," focusing on resisting the attention economy by withdrawing attention from productivity-driven frameworks and reinvesting it in the physical, public realm.
