5 Steps for Leaders & Rebel Technologists To Make an Impact in a Legacy Business

Legacy businesses are built on time-tested traditions, resilient systems, and a deep sense of purpose.

Walking into these environments as a change agent isn’t about tearing it all down, it’s about unlocking new potential with reverence, vision, and care. As a Rebel Technologist, your role is to spark evolution, not revolution.

Here’s how you make that kind of impact: sustainably, empathetically, and powerfully.

1. Start With Respect: Understand the Work That’s Come Before

Legacy doesn’t mean outdated. It means earned.

Start by listening. Learn the story behind the processes, the technology, the culture. Deeply understand what’s been built, who built it, and why.

This isn’t about sentimentality, either. It’s about trust. Businesses rooted in decades of experience often carry customer loyalty, institutional knowledge, and operational resilience.

There’s untapped gold right there.

Leaders who honour the past aren’t looking back, they’re building forward with everyone on board.

Empathy isn’t a soft skill; it’s a power move.

“Transformation does not necessarily mean that one has to turn one’s back on values and practices developed by an organisation over several decades. Embracing change while reverently carrying the legacy … is a fine balancing act, but one that can mean the difference between sustained growth and innovation.”3

2. Map the Future: Quarterly Vision, Quarterly Action

Don’t show up with a five-year plan wrapped in buzzwords. Show up with a clear vision broken into tangible, quarterly progressions.

Use quarterly reviews not just for performance tracking, but for storytelling. Where did we start? What did we try? What did we learn? This rhythm of reflection and recalibration turns big changes into achievable journeys. It creates space for people to grow into the change, not resist it.

“Quarterly business reviews are vital for driving business growth because they provide a structured way to track performance, tackle challenges, and uncover opportunities … These reviews help you make informed decisions that drive progress and improve results.”4

Legacy transformation isn’t about pace. It’s about direction and discipline.

3. Communicate Like a Product Owner

“Empathetic leadership understands and addresses the fears, anxieties, and uncertainties that change can bring. By putting people first, businesses can foster a culture of trust and openness, paving the way for smoother transitions.”2

If you’re not talking, people are assuming and assumptions kill momentum.

Over-communicate. Break silos. Treat every stakeholder like a collaborator. Share your roadmap, your risks, your wins, and your rethinks.

And do it often.

Product ownership isn’t just for tech, it’s a mindset. Be transparent. Be obsessed with feedback loops. And make sure everyone knows where they stand in the journey.

When people feel seen and heard, they show up for the mission.

4. Make It Simple, Make It Beautiful

Legacy environments tend to grow in layers: one workaround stacked on another. Your job is to cut through that clutter.

Simplicity isn’t easy. It’s an act of design.

Whether it’s migrating to modern systems, integrating AI, or improving the way teams interact with tools, clarity wins. Great design isn’t just about look and feel. It’s about user trust, reduced friction, and signal over noise.

When you deliver something that just works, people remember how it made them feel: confident, empowered, capable.

“The greatest challenge for legacy migration is understanding and reconciling the current-state to the future-state … Legacy systems often have dated and undesirable architecture, a cumbersome user experience … The future-state should also consider long-term technical trends and feasibility as well as business considerations for digital product offerings and revenue streams.”6

5. Build With Diversity and Bring HR and Governance In Early

Speed and innovation thrive in diverse, cross-functional teams. Different disciplines, different backgrounds, different ideas: this is how new possibilities get unlocked.

“Engaging [employees] in the process of change ensures not only that the legacy is secured but also makes them a part of the organisation’s future … Innovating for a purpose, and building from past successes will help an organization negotiate many complexities of change.”3

But in legacy environments, moving fast doesn’t mean moving recklessly.

Engage HR early to align on people’s needs. Bring in governance to navigate access, compliance, and policy without roadblocks. These aren’t hoops, they’re accelerators if brought in early.

Diversity needs space to move. Your job is to clear the runway.

This Is the Work of a Rebel Technologist

It’s not about disrupting for disruption’s sake. It’s about evolving something important— – carefully, creatively, and courageously.

You’re not here to replace the old guard. You’re here to build on what’s been earned, with a vision that respects the past and leans hard into the future.

Respect deeply. Design simply. Communicate obsessively. Move purposefully.

That’s how you make a legacy business future-ready – one bold, empathetic step at a time.

AI’s Great Equaliser: Open Access As the Ultimate Game-Changer

AI will open up new opportunities for millions of small- and medium-sized businesses to become the new disruptors and more competitive than the largest corporations of today.

We’ve seen AI rush in as not just a gentle wave, but a transformative tsunami.

Once guarded fiercely by tech giants behind lofty walls of exclusivity, AI is now within reach of almost everyone.

Welcome to the era of true technological democratisation.

 

 

But what exactly does democratisation of AI mean? At its core, it’s about accessibility.

Indiscriminate access to near limitless intelligence.

Making powerful AI tools affordable, usable, and adaptable for businesses of all sizes, from startups in garages to SMEs in office parks, and even curious individuals tinkering on their laptops is the name of the game.

AI’s Cost Revolution: Power to the People

Consider this insane fact: just a year and a half ago, leveraging AI at the level of GPT-3.5 cost roughly $20 per million tokens. Fast forward to late 2024, and that cost was cut down to just $0.07 – a 280-fold reduction.

This isn’t just cost-cutting; this is a revolution.

Companies like OpenAI have played a crucial role by consistently lowering prices, reducing barriers, and enabling anyone, anywhere to harness generative AI’s potential.

The implication?

Startups no longer have to choose between investing in AI or keeping the lights on. Entrepreneurs can leverage AI-powered insights without burning through their runway.

VentureBeat just posted about how American Express is capitalising on Generative AI to achieve 40% fewer IT escalations and an 85% boost in travel assistance.

“… Interacting with IT – particularly chatbots – can be a frustrating experience. Automated tools can offer vague, non-specific responses or walls of links that employees have to click through until they get to the one that actually solves their problem,” says the author, Taryn Plumb.

By infusing generative AI into its internal IT support chatbot, Amex finally put this problem to rest.

“The chatbot now interacts more intuitively, adapts to feedback and walks users through problems step-by-step. Amex has significantly decreased the number of employee IT tickets that need to be escalated to a live engineer.”

Open-Source: Leveling the Playing Field

Closed AI models have traditionally held the upper hand. Until now.

Open-weight models like Meta’s Llama are rapidly closing the performance gap.

In January 2024, open-weight models lagged behind their closed-weight counterparts by 8%. Just one year later, the difference shrunk to a mere 1.7%.

Open-Weight Models are also better for the environment:

  • Increased Transparency and Accountability: Public scrutiny can help identify and address potential biases or ethical issues in the model.
  • Facilitates Research and Innovation: Allows researchers to build upon existing work and develop new applications for the model.
  • Promotes Collaboration: Encourages community-driven development and improvement of the model.
  • Lower Barrier to Entry: Enables users to leverage advanced AI capabilities without the need for extensive development resources or specialized knowledge.
  • Flexibility and Customisation: Users can adapt the model to their specific needs by fine-tuning the weights.

This convergence means innovation is no longer restricted to the select few with hefty budgets and exclusive access.

Today, innovation belongs to everyone willing to explore, experiment, and evolve.

Decentralisation: The Rise of Autonomous Networks

Blockchain isn’t just about cryptocurrencies, it’s also reshaping AI.

Decentralised AI networks, such as the Thames Network, put power back into the hands of individuals. These blockchain-driven systems emphasise privacy, autonomy, and censorship resistance, encouraging a future where AI isn’t dominated by a handful of tech giants, but instead driven collaboratively by an inclusive community.

A Shift from Training to Leveraging

Interestingly, Stanford’s influential AI Index in 2024 spotlighted rising training costs for models like GPT-4 (approximately $78 million).

But, what it missed was the rapidly declining cost of AI inference and the explosive rise of open-weight models. The focus is shifting from training prohibitively expensive frontier models to leveraging widely accessible and affordable AI technologies.

This shift is monumental, emphasizing practical innovation over mere bragging rights of size and scale.

What Does This Mean for Businesses?

The democratisation of AI opens a floodgate of opportunities for businesses:

  • Innovation Acceleration: Smaller businesses can now experiment rapidly, iterate frequently, and innovate boldly, unencumbered by prohibitive costs.
  • Tailored Solutions: Businesses can leverage customisable open-source models, allowing for solutions precisely tailored to their unique challenges.
  • Competitive Advantage: Democratisation levels the playing field, enabling SMEs to compete against industry giants by smartly integrating AI into their operations.

Societal Impact: Inclusive Innovation

The broader societal implications are profound. Lower barriersmean increased innovation across sectors like healthcare, education, and the creative arts.

Individuals previously priced out of AI innovation can now become active contributors, innovators, and disruptors.

Yet, democratisation isn’t without its challenges:

  • Privacy: Decentralised systems must balance openness with robust privacy controls.
  • Standardisation: The lack of unified metrics can make evaluating different AI solutions complex.
  • Ethical Considerations: Responsible use of democratised AI must be a priority to avoid perpetuating biases or misinformation.

So, What’s Next?

If you’re in leadership or innovation, it’s crucial to reflect:

  • Are you leveraging the democratised AI tools now available?
  • Are you building a team of adaptable, AI-savvy generalists capable of thriving in this accessible AI landscape?
  • Are you fostering a culture of experimentation, agility, and ethical responsibility?

We’re past the age of exclusivity, and now fully in the imagination age. In this era, the currency of success is adaptability and democratised AI is its catalyst.

Final Thoughts from a Rebel

The future isn’t built by gatekeepers, it’s forged by rebels.

The democratisation of AI isn’t just technological advancement; it’s a clarion call for a new generation of rebel generalists and adaptable thinkers.

So, let’s lean into this messy, dynamic new world.

Let’s embrace AI’s democratisation to fuel creativity, innovation, and meaningful disruption. Because the future, more than ever, belongs to the curious, the adaptable, and the rebel technologists.

Will AI Replace Programming? Not Quite… The Future of Developers in an AI-Driven World

Hey fellow rebels and tech enthusiasts!

I’ve been deep in the AI and coding trenches lately, watching this revolution unfold in real-time.

The question on everyone’s mind: “Are we coding ourselves out of jobs?”

Let me share what I’m seeing from the front lines.

The AI Coding Revolution Is Already Here

If you haven’t paired with an AI coding assistant recently, you’re missing out on a paradigm shift.

Just yesterday, I watched as Copilot generated the core components of an authentication system from a few commented requirements. Three years ago, that would have taken hours—now, it’s done in minutes.

What’s happening isn’t just incremental, it’s exponential. These tools now:

  • Complete complex functions with impressive accuracy (though still require review)
  • Assist in refactoring legacy code that would make most developers cringe
  • Translate well-defined business requirements into functional code (with some gaps)
  • Help debug issues quickly, sometimes faster than senior engineers
  • Generate test suites that catch common edge cases (but don’t replace human intuition)The game has fundamentally changed. Full stop.

Two Competing Futures: The Great Developer Divide

The developer community is split on where this leads us. Check out these two perspectives that capture the tension:

 

Laura Wendel’s visualization stopped me in my tracks when I first saw it. That S-curve perfectly captures what many of us are experiencing: simple apps have become trivially easy to build, while complex systems might actually become harder to develop as our understanding of foundational code erodes.

I call this the “knowledge atrophy risk”—when you outsource your thinking to AI, those muscles weaken. How many phone numbers do you remember now that they’re all stored in your smartphone?

On the flip side:

 

 

Vijay’s historical perspective resonates deeply with me. Every major abstraction in tech history( from punch cards to assembly to high-level languages to cloud computing) didn’t eliminate programmers. It elevated what we could build.

His comparison to MidJourney prompts is spot-on.

I’ve watched designers transition from fighting against AI to embracing it as a creative partner by learning to “speak its language.” The same evolution is happening with developers right now.

The Acceleration Is Mind-Blowing

Want to understand how fast this is moving? Listen to OpenAI’s Chief Product Officer, Kevin Weil:

“I mean, at the rate that we’re going, I would be surprised if it’s 2027. I think it’s going to be sooner. O1, when it launched, our first like real launch of a coding model was something like the thousandth best engineer in the world. Add competitive coding contests. O3, which is coming soon, according to the same benchmarks, is the 175th best competitive coder in the world. And as we are starting to train, you know, the successor models, they’re already better.

And so I think this is the year that at least by the competitive coding benchmark, this is the year that that AI becomes better than humans at competitive code forever.”

Let that sink in. We’re months, not years, away from AI outperforming the world’s best human competitive coders. Forever.

My Journey: From Skeptic to Strategic Adopter

I’ll be honest, I was initially defensive when AI coding tools emerged. “They’ll never understand the nuance of what we build,” I thought.

Then I watch these videos of developers use AI to accomplish in a day what would have taken me a week as a junior dev.

That’s when it clicked: fighting this wave is like arguing with electricity. The question isn’t if AI will transform programming, it’s how we’ll transform ourselves alongside it.

The True Value of Human Developers in an AI World

Despite these advances, I remain bullish on the future of human developers for three crucial reasons:

1. Problem Discovery Trumps Problem Solving

In my fifteen years building products, I’ve learned that identifying the right problem is infinitely harder than implementing a solution. AI excels at answering questions but struggles with asking the right ones.

When I sat with healthcare clients last month, understanding their workflow challenges required empathy, domain knowledge, and interpersonal intelligence that no AI possesses.

The coding was the manageable part.

2. System Thinking Can’t Be Prompted

Enterprise architecture requires understanding how complex systems interact: technical, human, regulatory, and business.

I recently watched a team spend weeks trying to use AI to generate a complex financial system, only to scrap it all when they realised the AI couldn’t grasp the regulatory nuances that made their business viable.

Some knowledge can’t be easily encoded in a prompt.

3. Innovation Requires Human Leaps

Every framework that AI can now generate was originally created by human developers making conceptual leaps. React, TensorFlow, Kubernetes – these weren’t inevitable evolutions; they were creative disruptions.

AI models are trained on existing patterns. They excel at interpolation, but struggle with extrapolation. The next paradigm shift will still come from human creativity.

How I’m Adapting My Team for the AI+Human Future

At our core, Rebel Technologists embrace change rather than fear it. Here’s how we’re evolving:

  1. Reframing developer interviews: Instead of whiteboard coding exercises, we now focus on prompt engineering, system design, and problem framing. Can candidates direct AI effectively? That’s more valuable than memorising algorithms.
  2. Investing in domain expertise: Our most valuable developers aren’t the fastest coders, they’re those who deeply understand our customers’ industries. Technical skills with domain knowledge is the unbeatable combination.
  3. Building AI-native workflows: Rather than bolting AI onto existing processes, we’re designing workflows where humans and AI each play to their strengths. Our documentation, code review, and even architecture discussions now assume AI participation.
  4. Creating intentional learning paths: With simple tasks automated, we’re crafting deliberate learning experiences to ensure developers still understand fundamentals. Like pilots who train without autopilot, developers need to know what’s happening under the AI’s hood.

Thriving in the New Reality

For individual developers navigating this shift, my advice is straightforward:

  • Become the bridge between business problems and technical solutions
  • Master prompt engineering as a core skill
  • Build your domain expertise in at least one vertical
  • Develop your system thinking abilities
  • Lean into what makes you uniquely human: creativity, empathy, and ethical reasoning

The most dangerous place to be is in the middle: better than a beginner, but not as good as an expert. AI will squeeze that middle first, driving developers either upmarket (strategic thinking) or downmarket (implementation specialists guiding AI).

The Future I See Coming

I believe we’re entering the most exciting era of software development in history. The code we’re writing today will seem as primitive as assembly language in a few years.

As barriers to entry fall, we’ll see an explosion of software creation from previously excluded populations. The next great developer might be a nurse who uses AI to build healthcare tools no traditional programmer would think to create.

The partnership between humans and AI will unlock applications we can barely imagine—systems that adapt in real-time to changing conditions, interface with humans through natural language, and solve problems too complex for either humans or AI alone.

This isn’t the death of programming. It’s programming’s renaissance.

Will AI replace programmers? No. But programmers who use AI will absolutely replace those who don’t. The future belongs to rebels who embrace this transformation and ride the wave rather than being swept away by it.

What’s your experience building with AI so far? Has it changed how you approach development?

Drop your thoughts in the comments! I’m fascinated to hear how other technologists are navigating this shift.

Get Ahead of the Competition with Generative AI: The Technology That’s Changing Everything

We’re diving into the fascinating world of Generative AI or large language models (LLMs).

ChatGPT, Bard, Notion AI. If you’ve been keeping an eye on the field of natural language processing (NLP) lately, you’ve probably been roped into the buzz surrounding these sleek AI models.

But what exactly are they, and how do they work?

You’re King Arthur, The Generative AI Is Merlin

Think of it like this, large language models are basically AI wizards capable of conjuring up human-like language. 

Using these digital literary sorcerers, you’re given the ability to cast spells through the power of machine learning. But they’re not just pulling phrases out of thin air – they’re trained on these massive amounts of text data, like books, articles, code and websites.

During the training process, these models act like sponges, soaking up all the patterns and structures of language they can find. Once they’ve soaked up enough, they can spit out new text that looks like it was written by a human.

In fact, some portions of this post have been conjured by ChatGPT.

These models have been trained on so much data, theycan do all sorts of language tasks, like translation, summarisation, and question-answering. 

 

So, How Do They Do It? 

The process can be broken down into three stages: 

  • Pre-training,
  • Fine-tuning, and
  • Inference.

Pre-Training: During pre-training, the model learns from vast amounts of text data that stems from a variety of sources. This can include books, articles, and websites. 

The goal of pretraining is to teach the model to recognise patterns and structures in language, such as word meanings, grammar rules, and syntax. To make this work, a machine learning technique called unsupervised learning is used, which means that the model is not given explicit instructions on what to learn, but rather it uses statistical analysis to identify patterns and relationships in the data. 

Pre-training can take weeks or even months, depending on the size and complexity of the model.

Fine-Tuning: Once the model has been pretrained, it can be fine-tuned forspecific language tasks, such as language translation, summarisation, or question-answering. 

Fine tuning involves training the model on a smaller, more specific dataset that is tailored to the task at hand. 

For example, if the goal is to create a chatbot, the model can be fine-tuned on conversational data to learn how to generate appropriate responses to user inputs. During fine tuning, the model is tweaked and optimised to perform the specific task as accurately as possible.

Inference: Finally, during inference, the model generates new text based on what it has learned during pre-training and fine-tuning. 

Inference involves inputting a prompt or query into the model and then generating a response or output based on the patterns and structures it has learned. 

For example, if the model has been trained on news articles, it could generate a news article summary when given a longer article to process. The quality of the output during inference depends on the accuracy and specificity of the pretraining and fine tuning data.

One of the coolest things about large language models is that they can perform multiple language tasks with just one model. That means you can have a model that’s trained on translation data, but can also summarise and answer questions. 

It’s versatility in its finest, sleekest form.

 

Concerns About the Ethical Implications of These Models. 

The adage, “With great power comes great responsibility” couldn’t ring more true. Especially where the use of AI is concerned. 

With the versatility that these LLMs offer, complications surrounding the ethical use of tools like ChatGPT need to be considered.

Here are a number of ethical implications that these models come with: 

  1. Misinformation: One ethical concern is that large language models may generate or propagate false or misleading information, which could have serious consequences for individuals or society as a whole.
  2. Bias: Another potential issue is that the models may perpetuate or even amplify existing biases or prejudices in language, which could harm marginalised groups or reinforce stereotypes.
  3. Privacy: There are concerns that large language models may pose privacy risks, especially if they are trained on sensitive or personal data, such as medical records or financial information.
  4. Regulation: Given the potential risks associated with large language models, there may be a need for regulatory oversight to ensure that they are being used responsibly and ethically.
  5. Accountability: It may be difficult to hold large language models accountable for their actions or outputs, especially if they are highly complex and opaque. As such, there is a need for greater transparency and explainability in how these models are developed and used.

Researchers are, however, working on making these models more transparent and accountable, so we can reap the many benefits without any shady side effects.

 

Want To Learn More About Generative AI?

Large language models are transforming the field of natural language processing and enabling a wide range of language tasks to be performed with human-like accuracy. 

However, as with any powerful technology, there are also concerns about their ethical implications. 

Thus, it’s absolutely crucial that we continue to explore and understand the potential risks and benefits of these models, as well as ways to make them more transparent and accountable.

To learn more about large language models and ChatGPT, we’ve got a variety of informative (and practical) articles, as well as videos available on our blog and on Udemy.

Brett St Clair’s Udemy courses on ChatGPT are a great resource for anyone interested in learning more about these models and how they work.

So dive in, learn more, and make informed decisions about the future of NLP.
