Quantum Computing is nearer than thought. I will about it more.
When the Future Starts Knocking Quietly
I recently had a long and stimulating conversation with someone I had not met before. His name is James Myers, publisher of The Quantum Record and a Canadian accountant with a deep interest in how our systems of value and knowledge have developed. What began as an exchange on accounting and trust turned into a wake-up call about something I had been treating as distant: quantum computing. ## From Numbers to Trust Our first topic concerned how societies record value. Accounting seems technical on the surface, but beneath every entry lie choices about what matters, what lasts and what deserves protection. We discussed trust, the vulnerability of democracy and the way financial systems can drift away from the tangible world they are meant to represent. What’s the Value of Time in the Digital Era? In the Long Run, Slowing Down and Being Bored Can Produce a Wealth of Benefits - The Quantum RecordAI promises to create value by speeding work, but maybe far greater future value can be generated by taking a break for creativity.The Quantum RecordJames Myers ## A Shift in Perspective Late in the conversation, James introduced his current focus. He writes about quantum computing. I had assumed this was a distant horizon, still confined to laboratories. He challenged that view. The landscape is changing sooner than many realise. ## Identity and the Quantum Threat One concrete example changed my sense of timing. Germany has begun issuing identity documents designed to be resistant to attacks from quantum computers. Cyber security experts have been preparing for this shift for years, yet most people in civic life have never heard of it. The foundations of digital trust can move long before the public sees them move. Post-Quantum Cryptography: Germany Prepares Next-Generation ID Cards for the Quantum Eraermany takes a global lead in digital security: Bundesdruckerei, Giesecke+Devrient, BSI, and Infineon develop the world’s first post-quantum–secure ID card technology—protecting citizens’ digital identities against future quantum-computer attacks.PR-COM ## Why This Belongs in Public Conversation This brought us back to our starting point. Value is not only what appears in books. It includes the continuity of trust across generations, and the systems that hold identity, privacy and public life together. Cryptography is part of that foundation. If quantum capability arrives in practice before it arrives in public attention, we will adapt only after the fact. ## A Beginning This article marks the start of a new enquiry for me. I want to understand what quantum computing means for societies that depend on trust. I plan to look at what is becoming possible, who is preparing and where we still have choices. I am grateful that James encouraged me to take this seriously. We agreed to continue working together. With his support I will write foundational pieces that help me get a firm grip on the technology, while also beginning to reflect on the implications for the systems that keep our societies stable and free.

Cybernetics had nothing to do with computers.

It was Ancient Greek for helmsman.

And yet it became the basis for “cyberspace”, “cybercrime” and our digital world.

I'll show you how that happened:

Excel and the future cockpit of business logic
Excel has always been more than a spreadsheet. For decades it has been the place where business logic quietly lives. Not in software systems designed for control, but in the free space where analysts, planners and managers actually think. What interests me today is how this space is changing as AI becomes a co-worker rather than a tool. And why Microsoft’s CEO Satya Nadella keeps returning to Excel when he talks about the future of knowledge work. It suggests that spreadsheets are not a relic of a pre-AI world. They may become one of the primary surfaces where humans steer autonomous agents. ### What spreadsheets already are A spreadsheet is a modelling environment. It shows reality and scenarios at once, across time and uncertainty. It is where risks, margins, and alternatives can co-exist and be compared. It is also a subtle form of programming without the ceremony: a model emerges step by step, and the “code” is simply what the sheet becomes. Nadella makes this explicit when he calls spreadsheets **Turing complete**. In principle they can express any logic a general computer can. Which means they are not just containers for numbers. They are a programming language that millions know by instinct, without naming it as such. > Excel Agent is not a UI-level wrapper. It’s actually a model that is in the middle tier. … I have a full understanding of all the native artifacts of Excel. Because if you think about it, if I’m going to give it some reasoning task, I need to even fix the reasoning mistakes I make. That means I need to not just see the pixels, I need to be able to see, ‘Oh, I got that formula wrong,’ and I need to understand that. - Satya Nadella. ### Rows, columns and the human mind There is a reason this format never felt like learning a new skill. Tables appear across all recorded history. They give us a humane geometry for complexity. Rows group cases, columns define attributes, and the grid allows order without forcing abstraction too early. You can just see what is happening. That deep familiarity matters. New interfaces rarely displace structures that are shaped by human cognition. ### Excel as the IDE we already use Nadella pushes the idea further. He calls Excel an IDE for people who are not thought of as programmers. In software development the IDE is the cockpit where you run, test, and inspect the behaviour of code. Something similar happens in Excel: forecasting, checking dependencies, tracing errors, comparing scenarios. And that cockpit becomes even more important when thousands of AI agents are working in parallel. He describes a shift from **micro execution** to **macro delegation, micro steering**. We will give missions to agents, then watch for anomalies, approve changes, redirect effort. The work will be choosing what matters, not executing each step. For that you need a surface where the structure is visible and steerable. Something like a spreadsheet. ### The sheet joins the workflow This is not about adding AI features to an old tool. It is about moving business logic into a live environment where AI participates: • agents draft projections and proposals directly in the grid • humans intervene at the right moments • the surface shows risk, uncertainty, and alternatives • acceptance and rejection become learning signals for the model In this reading, Excel is not being replaced. It is completing a long arc. From modelling… to programming… to a place where humans and agents collaborate in real time. ### The question that follows If the spreadsheet becomes a cockpit for autonomous agents, what does that mean for governance, for transparency, for the authority of human judgement? We are not only updating a tool. We are updating the boundary between what people decide and what systems propose. The table might remain familiar, but the activity inside it will feel new. It is worth paying attention. The future of AI in organisations may not arrive as a new interface. It may arrive in the grid we already trust. * * * Excel, the Hidden Operating System of Business ReasoningExcel has long been the silent operating system of business reasoning. AI may be about to extend that logic into natural language.Rob HoeijmakersRob Hoeijmakers

If you are exploring the possibilities of AI, you can’t ignore Excel.

That is where companies and organisations often have the most interesting logic, rules and data.

It seems my blog, published through @ghost.org, also appears here on BlueSky. Thanks to ActivityPub and some mysterious bridge from the Fediverse.

I don’t fully understand how it works yet, but it’s nice to see it showing up. I’ll look into it a bit more later.
