What would a world look like where developers have been replaced by AI?

Lately, we keep hearing in mainstream media about AI models so powerful that they will replace developers. Those of us who are well-informed know this is largely a marketing tactic to fuel the hype around AI and attract investment into the technology. But have you ever stopped to think about what this would actually mean?

What would a world really look like where 100% of developers’ work is replaced by AI agents?

As Plato would say, “Let us examine (Episkepsómetha).”

Let’s start by examining why companies have developers in the first place. There are many reasons (such as security, maintenance, etc.), but let’s focus on the two clearest cases:

1. Because it is a software company (such as a SaaS business)
2. Because it is another type of company that wants to automate or improve efficiency in its internal processes

To simplify, let’s focus only on the second case.

What would it mean to live in a world where 100% of your developers’ work is covered by AI? In other words, a world where every non-software company has access to an unlimited army of developers.

Before we continue, let’s be explicit about something: this is a strong and extreme hypothesis. We are deliberately pushing the idea to its limit, not because it is the most likely outcome, but because it helps us clearly visualize the implications of such a world.

If we fully embrace this extreme scenario, unlimited development capacity would imply the ability to automate virtually everything. All processes within a company could be automated and optimized for efficiency: payroll, billing, customer support, internal operations… even highly complex workflows.

Companies would have such brute-force capability that nothing would realistically escape automation. In that sense, a world with unlimited development power—a world without developers—would also imply a world where finance teams, customer support, operations, and even parts of management as we know them today would largely disappear or be radically transformed.

This leads to an interesting conclusion: developers can, to some extent, feel reassured. If such a scenario were ever to happen, their role would likely be among the last to be fully automated.

However, "With great power comes great responsibility". The role of developers is already changing—and will continue to change profoundly. Developers are gradually shifting from being pure coders to becoming orchestrators of AI-driven systems: designing workflows, coordinating agents, validating outputs, and ensuring that systems behave as intended.

With this change of paradigm, if an engineer wants to remain relevant, it will not be enough to simply write code. They will need to: Understand how to validate AI-generated outputs critically, develop expertise that combines technical knowledge with business domain understanding, learn how to design, guide, and supervise AI systems effectively, etc.

Finally, it is important to come back to reality. Everything described above represents an extreme scenario, a thought experiment. We are not necessarily heading toward a world where everything is fully automated. Instead, what we are already starting to see is more interesting: Developers will become significantly more productive and teams will become smaller but more impactful.

In fact, the Spanish job market already reflects this trend. In early 2026, developer job openings have increased, with leading employment platforms reporting a growth of 25% compared to the end of 2025.

So rather than disappearing, developers will evolve. They will not be replaced, they will be amplified. And those who learn how to work with AI, rather than against it, will be the ones who shape what comes next.
