Worry about the dumb machines as well as the smart ones

Worry about the dumb machines as well as the smart ones

We have been warned about the dangers of intelligent machines for over 150 years. In his satirical novel Erewhon by Samuel Butler, published in 1872, the protagonist visits a mythical country where machines have been outlawed. The novel quotes the fictional Book of Machines, the supposed trigger for a civil war between ‘machinists’ and ‘non-machinists’: I fear none of the existing machines; what I fear is the extraordinary rapidity with which they are becoming something very different to what they are at present. No class of beings have in any time past made so rapid a movement forward.

There's always a bigger goat: don't let big problems stop you solving smaller problems

There's always a bigger goat: don't let big problems stop you solving smaller problems

In the story of the three billy goats gruff, the goats want to cross a bridge guarded by a troll. They manage this by each telling the troll that there is a bigger goat just behind them until (spoiler alert!) the biggest goat comes along and butts the troll into the sky.

Sometimes, when we are trying to make the case for enterprise technology capabilities, it feels like we are the trolls, and that we are so scared of the biggest billy goat that we won’t tackle the smaller goats. When we look across our technology landscapes, we see mess, waste and mayhem, and wish that we had some of the foundational capabilities that would help clean things up. Yet we hesitate, because we know that every time we build something we will uncover another problem, and another problem, and another problem, until we get to problems that are so big that we cannot imagine how to solve them.

The language illusion, doubled

The language illusion, doubled

Is programming a computer more like language or more like maths?

Neither, it turns out. In recent research, neuroscientists at MIT conducted brain scans of programmers while they were trying to solve problems, and discovered that, rather than engaging the language centres of the brain, they engaged a system known as the multiple demand network, usually used for complex problem solving.

Programming languages, it seems, are not the same as ordinary languages. This is not new news. In the earliest days of programming, when Grace Hopper was inventing high level languages, she and her team sent versions of their code to their bosses in French and German. The bosses sat up and paid attention: was it possible that their computers had suddenly learnt to speak foreign languages?

Technologists are always crying wolf (because of all the wolves)

The computer had failed. Unfortunately, it was the Apollo Guidance Computer (AGC), the machine that controlled the flight of a small, fragile spacecraft to the Moon and back. Fortunately, it wasn’t in space: it was on the ground, in a simulator.

Margaret Hamilton, the leader of the MIT team programming the AGC, often had to work weekends to meet the urgent schedule of the Apollo programme, and sometimes brought her daughter, Lauren, to work with her. Lauren liked to play in the simulator.

Coping with volatility: don't panic; seek truth; release frequently

Coping with volatility: don't panic; seek truth; release frequently

If you’re in the last stages of a multi-year digital delivery programme, then you probably feel frazzled. That’s the normal condition of late stage programme teams. If your programme has coincided with the last five years (five year digital delivery programmes are still a thing) then you must feel frazzled to a historic degree.

It’s more complicated on the inside than it is on the outside

It’s more complicated on the inside than it is on the outside

We don’t need time machines to create paradoxes in technology: they are built into the way we work. One of these paradoxes is that the simpler technology appears on the outside, the more complicated it is on the inside.

I was reminded of this recently when talking to someone who confidently told me that the more sophisticated AI models get, the easier they will be to use, for technologists as well as end users. AI would solve its own skills problem. I was surprised by this because, to me (and, I expect to most other technologists), while we understand how natural language interfaces can radically simplify the experience for end users, the introduction of the current wave of AI into our architecture makes it more complicated.

Learn to fail fast? Technologists fail all the time

Learn to fail fast? Technologists fail all the time

From time to time, organisations attempt to learn new ways of working. They attempt to become digital or agile or data-driven or innovative. These attempts come with some familiar ideas: that we should execute through cross-functional teams who are empowered to experiment. One of these ideas is that we should not be scared of failure, and that we should learn to fail fast.

These attempts sometimes elicit eye rolls from the technology teams, especially the idea that we should embrace failure. This is not because these ideas are invalid: in fact, they are welcome to technology teams, and reflect their preferred ways of working. However, technologists have a different relationship with failure than non-technologists.

Are LLMs the air fryers of AI?

Are LLMs the air fryers of AI?

Do you know someone who got an air fryer for Christmas? Or did you get one yourself?

If you know someone who got an air fryer, then there’s a high chance that you have heard all about it, and how it has been a complete game changer. They can cook things in a fraction of the time it used to take! And it’s not a fryer at all - it’s really a mini-oven! If you got an air fryer yourself, then there’s a chance that you’ve used it for everything, and that, even now, you are thinking about what you could use it to cook next.

I don’t have an air fryer myself, but am old enough to remember when my family first got a microwave. We lived off jacket potatoes for at least a week, and tried microwaving many things that should not be microwaved (there’s a reason that roasts are called roasts). Eventually, we found, just as my friends with air fryers seem to be finding in the weeks after Christmas, that, while the microwave is a useful tool to have in the kitchen, it’s not the only answer, and certainly not the best answer for everything.

On the 2025 to-do list: figure out AI agents

Recent years have seen waves of AI innovation breaking faster than we can figure out good practice. Organisations around the world are working hard, not only to find ways to put AI to work, but to do so safely and responsibly. The AI to-do list often seems to be growing longer faster than we can strike items off it - but the only route to good practice is practice.

The advent of AI agents promises to add more items to the to-do list. The AI agent wave started cresting in 2024, and will break in 2025. Several major technology vendors and platforms already offer their customers the ability to build, configure and operate AI agents in an enterprise context, and the ability for consumers to build agents or to subscribe to existing agents, cannot be far behind (indeed, it is likely that, by the time this article is published, it will already be happening).

Thinking differently about . . . machine learning

Thinking differently about . . . machine learning

Have you ever been introduced to someone then, five minutes into the conversation, realised that you can’t remember their name? If you have never had this experience, then you have a better memory than mine. Whenever that happens, it feels as if you have a window of acceptable ignorance -  a period during which it’s embarrassing but not disastrous to admit your lapse of memory. But, as time goes on, you can feel that window expiring: it becomes more and more awkward to ask the person’s name.

It can feel like this in enterprise technology too: we hear about new technologies, trends and terms every day, and there’s a period during which it seems fine to admit that you don’t understand, and to ask people to explain. But then the new concepts are everywhere, and everybody seems to using them with confidence. How did you get left out? Is it okay to say ‘I don’t understand’ now, or is it too late?

I have to admit that I felt like this for a while with the concept of machine learning.

Cloud leadership: the director

Cloud leadership: the director

I believe two apparently contradictory things about Cloud transformation (and other ambitious change programmes). First, I believe that the best way to get things done is through small teams of smart experts with as much autonomy as possible. Second, I also believe that the best way to get things done is with clear leadership and direction, and the exercise of programme management disciplines, many of which might seem old-fashioned.

How do we reconcile autonomy and empowerment with clear leadership and disciplined programme management? Is there a role for classic programme management skills in a world of agile practices? Answering these questions is the job of one of the seven key leadership roles for Cloud transformationthe Director. The Director is the person who leads and organises, who sets priorities, goals and metrics, who creates structure and discipline.
