This article is part of a series on the Sens-AI Framework—practical habits for learning and coding with AI.

A few decades ago, I worked with a developer who was respected by everyone on our team. Much of that respect came from the fact that he kept adopting new technologies that none of us had worked with. There was a cutting-edge language at the time that few people were using, and he built an entire feature with it. He quickly became known as the person you’d go to for these niche technologies, and it earned him a lot of respect from the rest of the team.

Years later, I worked with another developer who went out of his way to incorporate specific, obscure .NET libraries into his code. That too got him recognition from our team members and managers, and he was viewed as a senior developer in part because of his expertise with these specialized tools.

Both developers built their reputations on deep knowledge of specific technologies. It was a reliable career strategy that worked for decades: Become the expert in something valuable but not widely known, and you’d have authority on your team and an edge in job interviews.

But AI is changing that dynamic in ways we’re just starting to see.

In the past, experienced developers could build deep expertise in a single technology (like Rails or React, for example) and that expertise would consistently get them recognition on their team and help them stand out in reviews and job interviews. It used to take months or years of working with a specific framework before a developer could write idiomatic code, or code that follows the accepted patterns and best practices of that technology.

But now AI models are trained on countless examples of idiomatic code, so developers without that experience can generate similar code immediately. That puts less of a premium on the time spent developing that deep expertise.

The Shift Toward Generalist Skills

That change is reshaping career paths in ways we’re just starting to see. The traditional approach worked for decades, but as AI fills in more of that specialized knowledge, the career advantage is shifting toward people who can integrate across systems and spot design problems early.

As I’ve trained developers and teams who are increasingly adopting AI coding tools, I’ve noticed that the developers who adapt best aren’t always the ones with the deepest expertise in a specific framework. Rather, they’re the ones who can spot when something looks wrong, integrate across different systems, and recognize patterns. Most importantly, they can apply those skills even when they’re not deep experts in the particular technology they’re working with.

This represents a shift from the more traditional dynamic on teams, where being an expert in a specific technology (like being the “Rails person” or the “React expert” on the team) carried real authority. AI now fills in much of that specialized knowledge. You can still build a career on deep Rails knowledge, but thanks to AI, it doesn’t always carry the same authority on a team that it once did.

What AI Still Can’t Do

Both new and experienced developers routinely find themselves accumulating technical debt, especially when deadlines push delivery over maintainability, and this is an area where experienced engineers often distinguish themselves, even on a team with wide AI adoption. The key difference is that an experienced developer often knows they’re taking on debt. They can spot antipatterns early because they’ve seen them repeatedly and take steps to “pay off” the debt before it gets much more expensive to fix.

But AI is also changing the game for experienced developers in ways that go beyond technical debt management, and it’s starting to reshape their traditional career paths. What AI still can’t do is tell you when a design or architecture decision today will cause problems six months from now, or when you’re writing code that doesn’t actually solve the user’s problem. That’s why being a generalist, with skills in architecture, design patterns, requirements analysis, and even project management, is becoming more valuable on software teams.

Many developers I see thriving with AI tools are the ones who can:

Recognize when generated code will create maintenance problems even if it works initially

Integrate across multiple systems without being deep experts in each one

Spot architectural patterns and antipatterns regardless of the specific technology

Frame problems clearly so AI can generate more useful solutions

Question and refine AI output rather than accepting it as is

Practical Implications for Your Career

This shift has real implications for how developers think about career development:

For experienced developers: Your years of expertise are still important and valuable, but the career advantage is shifting from “I know this specific tool really well” to “I can solve complex problems across different technologies.” Focus on building skills in system design, integration, and pattern recognition that apply broadly.

For early-career developers: The temptation might be to rely on AI to fill knowledge gaps, but this can be dangerous. Those broader skills—architecture, design judgment, problem-solving across domains—typically require years of hands-on experience to develop. Use AI as a tool, but make sure you’re still building the fundamental thinking skills that let you guide it effectively.

For teams: Look for people who can adapt to new technologies quickly and integrate across systems, not just deep specialists. The “Rails person” might still be valuable, but the person who can work with Rails, integrate it with three other systems, and spot when the architecture is heading for trouble six months down the line is becoming more valuable.

The developers who succeed in an AI-enabled world won’t always be the ones who know the most about any single technology. They’ll be the ones who can see the bigger picture, integrate across systems, and use AI as a powerful tool while maintaining the critical thinking necessary to guide it toward genuinely useful solutions.

AI isn’t replacing developers. It’s changing what kinds of developer skills matter most.
