EXPLORATORY SINGLE-CASE STUDY · DIGITAL LAB · KLAUS ARENT
A long-term observation of intensive use of generative AI in knowledge work
Since mid-2025 I have been documenting how working methods, productivity, decision load and project scope change when an experienced knowledge worker uses AI agents extremely intensively. Investigator and subject are the same person: me.
n = 1, self-reported, no control group. Study design and limitations: study design (German).
THE KNOWLEDGE GRAPH
The study's memory, relinked every night.
Every night at 3 a.m. an agent breaks the day's work into notes, links them and updates this graph. Only the anonymized topology is shown: dots and connections, no titles, no content. Curated main nodes are clickable.
8,966 NOTES · 17,347 LINKS · AS OF 2026-11-05 · UPDATED NIGHTLY AT 3 A.M.
01 COLLECTED DATA
These numbers measure activity, not success. Commits are filtered by author identity and deduplicated by hash; they include experimental and discarded changes. Deployment events include fixes and automated releases.
As of July 2026 · from my own git analysis across 101 repositories · total recorded across all repositories, including cloned third-party projects: 14,263

When almost everything becomes buildable, more has to die.
A catalog sells, but it retains nobody. After ten concept rounds the community won and the shop became a side note.
Gym-Verzeichnis2026 – 20267,368 thin location pages from raw data would have cost more visibility than they earned. Stopped before the first one went live.
HeroRanker2025 – 2026A passion project, but a shiny object. The next one was shinier.
