Jean-Paul Paoli opens with a scene: an employee spent an evening deciding a difficult question — accepting a job offer, gauging their own burnout — and did it with a chatbot. At the next one-on-one, the manager meets someone composed: the conversation that would once have surfaced the problem to a human has already taken place, with a machine. This is his thesis: the media's fear of AI at work is replacement, but "the silent outcome is worse, and it leaves everyone employed." People stay; what comes undone is what made them more than task executors.

The team is a fabric woven from threads; they are pulled one by one and the layoff count stays at zero while the fabric gives way. The phenomenon has become ordinary — Pew: roughly one in five US workers does at least part of their job with AI, and the share is climbing, driven by younger workers. Jing Hu notes that AI anxiety is an old identity question ("who am I if not my job?"): work is where people most want someone to talk to, and an entity that is always available and never puts you down is built to answer that need.

Paoli refuses to panic: the AI confidant "earns its place" (Galloway: the best personal ROI comes from AI as a thinking partner). But the value and the risk are the same feature: "always available" becomes "always first," "never judges" becomes "never challenges." The MIT Media Lab/OpenAI study (4M+ conversations) links emotional attachment to loneliness, and trust to dependency: "a matter of dose, not of kind."

Three threads come undone through the same door. Peer-to-peer bonds: the junior asks the model, not the senior — tacit knowledge stops circulating (a Business Horizons study confirms it). The bond with the manager: deprived of the raw version of problems, the manager becomes "the last to know instead of the first." Judgment: once output is no longer a signal, people stop developing those who know how to do the work and judge whether the machine is wrong; yet "judgment is not a soft skill, it's the most expensive thing a company knows."

Remedy: name itshadow intimacy, by analogy to Shadow IT — then re-weave deliberately (cultural diagnosis, conversations reserved for humans, manual work to build judgment). The retirement of GPT-4o (February 13, 2026, a petition with 20,000+ signatures, "more painful than a breakup") is a reminder that dependency only becomes visible when it breaks. "The colleague you didn't hire is already in the building."
