The End of Software as We Know It - When AI Kills the Logic Layer
Software has always had three layers:
The interface — how humans interact with it
The logic — the set of rules that drive its behavior
The data — the raw material that feeds it
For decades, the software industry has revolved around designing the logic layer — encoding business rules, modeling workflows, anticipating edge cases, and translating complexity into executable steps. That's what software companies have always been proud of.
The interface layer’s job? To reflect that logic in the most intuitive, accessible way possible. UI was the projection surface. Logic was the substance.
But now, this structure is collapsing.
The End of Predefined Logic
With the rise of AI agents and generative reasoning, we are witnessing the slow elimination of the logic layer as we know it.
Instead of being coded upfront, logic is now learned and adapted in real time. AI doesn’t follow a rigid script — it analyzes the context, understands intent, draws from data, and chooses what to do next.
And it doesn’t stop there.
These systems don’t just reason with existing tools — they can discover new tools, plug them in, and learn how to use them. They can redesign their own workflows. They can evaluate the impact of their decisions and self-correct over time.
The same goes for interfaces: They no longer need to be static. Interfaces can be redesigned dynamically, adapted to each user’s preferences, behavior, and intent — all in real time.
The logic becomes fluid. The UI becomes ephemeral. Everything starts bending to the context.
From “What Should the Software Do?” to “What Are We Trying to Achieve?”
Traditional software reduces reality into paths and parameters. AI doesn’t. It expands the solution space instead of narrowing it.
We are moving from deterministic flows to goal-based orchestration. The user expresses intent. The system reasons, acts, and adapts.
This turns the whole software paradigm on its head: We stop asking “What should the software do in this situation?” And we start asking: “What outcome are we aiming for — and what data and tools are available to get us there?”
What Happens When Logic Becomes a Commodity?
This shift is not a cosmetic update. It erodes the foundations of many software companies — especially those whose core product is business logic.
If logic is now generated dynamically, and interfaces adapt themselves — what’s left?
Here’s the uncomfortable conclusion: In the long run, only one layer retains value — the data.
Data becomes the foundation of context, the memory of past decisions, the signal for better reasoning. It’s what gives AI the power to personalize, adapt, and improve. It becomes the only true proprietary asset in the stack.
Interfaces? Commoditized. Logic? Commoditized. Data? Exponentially valuable.
A New Era of Software Design
This doesn’t mean software disappears. It evolves.
We stop designing fixed flows.
We start curating high-quality data and making it accessible in an AI-readable and highly secured way.
We architect systems where reasoning is emergent, not hard-coded.
We configure agent networks that learn, adapt, and collaborate.
In this new world, the software company isn’t the one with the most clever UX or business rules — It’s the one with the richest, cleanest, most relevant data.
Data Is Power. Who Controls It?
As the logic layer dissolves and interfaces become ephemeral, what remains — and grows in importance — is the data.
But not just owning data. Making it accessible. Curating it. Protecting it. The value of data compounds only if it can feed intelligent systems — and do so securely, transparently, and ethically.
This shift will also change how we view AI models themselves.
The logic inside LLMs — their ability to reason, plan, even act — will also become increasingly commoditized. But the data they are trained on? That’s where the real differentiation lies.
And here’s the paradox: today’s leading model builders — OpenAI, Anthropic, and others — extract value from vast amounts of data, often without paying much (or anything) for it. That imbalance hasn’t hit a breaking point yet. But it will.
As the economic and strategic value of training data grows, the question of who owns it, who controls it, and who gets paid for it will define the next decade of AI.
Data is no longer exhaust. It’s fuel. And in this new software stack, it’s the only piece that truly matters.
The future won’t belong to those who build the smartest logic. It will belong to those who understand what intelligence needs — and who can feed it, govern it, and secure it at scale.

3moMaybe it’s less that the logic layer vanishes, and more that AI is now the new ‘logic author’ in certain contexts—autonomously writing, adapting, and refining rules that humans previously hard-coded within configurations and settings (now AI is informed by data to be able to make those decisions with RLHF)

3moAs always, very insightful Rupert. Food for thought from someone at the forefront of this major shift. Thxs.

3mo100% Agree with Rupert Schiessl. It shows also that the need for software localization (UI) may change in many ways: either hyper-personalized per end-users and/or very generic in a way that everything might be piloted/managed by voice given that with AI voice recognition improvements, then the +50y existing keyboards and mouses become less and less relevant. AI-enabled voice agents might be the next step to kill the UI layer after the Logic Layer has vanished.
