Nikesh Arora (Palo Alto Networks CEO ) made a point in a recent podcast interview that has struck a chord: the AI moat is not the model. It is the memory layer.

On one level, this is becoming obvious. Frontier model capabilities are converging quickly, and token costs are collapsing on a steep curve. What looks differentiated today is likely to be widely accessible within a short planning horizon.

So the real constraint shifts.

Model access becomes commoditised. The durable differentiation moves into what sits above it: persistent, contextual knowledge about users, organisations, decisions, preferences, constraints.

That accumulated context is not trivial data. It is behavioural history encoded into a system that increasingly shapes outcomes. And it compounds.
Every interaction strengthens the system’s ability to anticipate, recommend, and execute within a specific enterprise environment. That creates switching costs that are not contractual - they are epistemic. You do not lose a tool. You lose continuity.

This is where the strategic implications get sharper.

The most important AI systems in enterprises will not be those with the best benchmark performance. They will be the systems that accumulate the deepest organisational memory and make it progressively harder to leave.
In that framing, procurement criteria that focus on features, model choice, or even near-term capability are miscalibrated. The more relevant question is: how much proprietary context does this system accumulate on our behalf, and how portable is it?

That shifts AI evaluation closer to network effects analysis than traditional software comparison. The product is no longer just intelligence. It is continuity.

Memory is becoming the primary vector of lock-in. Most organisations are still treating it as a secondary design consideration.
