We've Passed the
Inflection Point

The Inflection Is Behind Us

2022 → NOW
"The models are good enough. The limiting factor is now imagination and trust, not capability."
  • Compound improvement is the real story — each model is qualitatively different
  • Dark factories: lights-out AI production is already here
  • Automation timelines are 3× faster than 2023 predictions
  • LLMs are not search — they are reasoning engines

Three Eras of AI

speed on new domains
  • Era 1 (2022-23): Try it and be amazed
  • Era 2 (2024-25): Integrate into workflows — we are here
  • Era 3 (2026+): Entire pipelines run without humans
  • Each era requires different skills and mental models
Simon's ruleEvery 6 months the game changes enough to require unlearning. Stay uncomfortable.
Dark Factories

Lights-Out AI Production

  • Dark factory: No human in the loop, AI produces outputs continuously
  • Already real: Code generation, content pipelines, data synthesis at scale
  • What breaks: Quality control, accountability, copyright, trust chains
  • What's next: Agentic systems that spawn sub-agents to complete tasks
Who benefits first

Companies that already have structured data pipelines and evaluation infrastructure.

The risk

Dark factories with no evals are liability factories. Garbage in, garbage at scale.

Stay Relevant

How to Survive the Inflection

  • Use LLMs to learn new domains 10× faster — explore outside your expertise
  • Compound your skills: learn enough of 3 adjacent fields to be dangerous
  • Build eval habits now — knowing if the output is good is the critical skill
  • Don't build what LLMs can do. Build what requires judgment.

Hard Truths About the AI Transition

AI needs humans in the loopINSTEAD →Dark factories prove otherwise. The loop is becoming the exception, not the rule.
Learn to promptINSTEAD →Learn to eval. Prompting is table stakes; knowing if the output is right is the real skill.
Jobs are safeINSTEAD →Roles are being restructured. The work changes faster than job titles do.
AI is a toolINSTEAD →AI is a colleague. Tools don't hallucinate with conviction — AI does.
