Building a Software Factory: Merging 1000 PRs in a Week Both address how LLMs change software production economics and velocity, though at different scales — the new item focuses on personal tools while this covers industrial-scale PR throughput.
Vibe Coding's Evolution Into Mainstream Development Vibe coding's rise into mainstream development is the mechanism enabling non-professional developers to build polished personal tools, directly supporting the thesis that LLMs have lowered the barrier to app creation.
A Staff Engineer's Guide to Inventing Work Both examine how to identify and justify work worth doing in an era of changed tooling economics — the staff engineer's guide to inventing work parallels the question of what small tools are now worth building.

Supports

The Plunging Price of Thought The plunging price of AI inference directly enables the economics described — cheaper tokens make building personal-scale tools without monetization viable, as the cost to run LLM-powered apps drops toward negligible.
Tokens Too Cheap to Meter Tokens too cheap to meter reinforces the economic argument — when compute cost approaches zero, the calculus of building small tools shifts from needing revenue to cover costs to pure personal utility.
AI-pilling our company: lessons learned Lessons from AI-pilling a company echo the individual-level thesis: LLMs unlock new categories of useful tools that weren't worth building before, changing what gets created and by whom.
