I am not fully confident of the name coherence stack, my favorite alternative:
-
… people using AI are producing more stuff faster without any clear sense of whether the stuff is good or consistent …
-
… single person with the right tools can do what used to require a department.
- … AI can execute tasks that once demanded teams of specialists.
-
… economics that made large firms necessary are reversing.
-
… solopreneur’s …
- … advantage is coherence.
-
… coherence … : the degree to which every part of an operation derives from the same understanding, the same model of reality and set of priorities and tradeoffs.
- … entire loop happens inside one mind.
-
Every handoff loses information, every translation introduces drift, and every layer of abstraction moves further from ground truth.
-
Organizations have spent decades trying to solve this problem.
- … fighting against something that won’t budge:
- knowledge is sticky and context is lossy,
- and understanding doesn’t transfer perfectly between humans.
- … fighting against something that won’t budge:
-
… company starts small, with the founders doing everything themselves.
- … decisions quickly because they understand everything about the business, and the business works.
-
… hire people … transfer processes. … new employees don’t have the context that generated those processes …
-
… adding coordination mechanisms like project managers, alignment meetings, and cross-functional reviews.
-
… 2022 Microsoft study found … spend over 50% of their time on internal communication and coordination.
-
context fragmentation
-
… information isn’t understanding …
- Understanding = integration
- … integration happens in minds
- Understanding = integration
-
Each person reads a fragment, interprets it through their own context, and forms their own understanding.
- People don’t disagree on facts; they’re operating from different maps of the same territory.
-
… each employee has their own AI assistant, trained on whatever context they happen to feed it …
- AI amplifies individual perspectives rather than creating shared ones.
-
-
… operating alone, you have one context, one understanding, one model ..
-
… humans are good at integration and judgment …
- … AI is good at execution and volume …
-
… using AI to do random shit faster, you’re not capturing the advantage.
-
- … mind layer, which is you: your understanding, your judgment, your integrated model … layer can’t be automated or delegated, and it’s the source of coherence.
- context layer … documents that AI tools can consume. … your constraints and tradeoffs, your voice guidelines, your decision history.
- execution layer, where AI operates.
- output layer …nothing reaches this layer without passing through a coherence check:
- does this output reflect my model? Would I have produced something like this? Does it fit with everything else?
-
Most people using AI skip the context layer entirely.
-
context layer
- What problem do I solve, and for whom specifically?
- What’s my actual thesis for why my approach works
- What are the core tradeoffs I’ve chosen?
- … maintain a decision log. When you make a significant choice, write down what you decided and why.
- What do I explicitly not do?
- … build your constraints file.
- For example:
- … When choosing between comprehensive and focused, choose focused. …
- For example:
- … build your constraints file.
- How do I sound?
- Include examples. Point to a piece you wrote that exemplifies the voice, and one that doesn’t.
-
… short enough to include in AI prompts. … compression without loss of generative power.
-
Every output that ships should pass through a coherence check.
- You can automate part of this.
- Feed your AI tool your recent outputs and ask it to compare a new draft against them, flagging inconsistencies.
- … final judgment has to be yours.
-
anti-patterns that break coherence
- Context starvation … ask AI to do something without feeding it your operating model, your constraints, your voice.
- AI outputs without proper review … deviations accumulate.
- Model staleness … understanding evolves but your context documents don’t.
- Fragmented tooling = using different AI tools with different contexts.
- Decision amnesia = making choices without recording the reasoning.
-
… audit your operation for coherence as often as possible. … frequency matters less than doing it at all.
- … audit also reveals context layer gaps.
- Add constraints, add examples, make the implicit explicit.
-
… coherence advantage works best in domains where the value comes from understanding rather than from physical or regulatory scale.
-
… large organizations haven’t figured out how to respond. … give everyone AI tools and hope for productivity gains, which accelerates their fragmentation …
-
… transaction costs are collapsing …
-
Coasean logic that justified large firms is weakening.
- Coase Theorem
- Example: A factory pollutes a fisherman’s river. Whether the factory has the right to pollute, or the fisherman has the right to clean water, they will negotiate to the same efficient outcome — the one that maximizes total value. The initial assignment of rights only affects distribution (who pays whom), not efficiency.
- Coase Theorem
-
If there is a new moat (and I’ll admit, that’s a big “if”) it probably looks like coherence; the ability to operate as one mind, one understanding, one model, …
