Key Takeaways
- Adoption of AI in software development is high, but trust is low. Developers say debugging AI-generated code often takes longer than writing it themselves.
- Core coding skills are still essential. You need to know how to code to recognize and fix AI’s mistakes.
- Community still matters. When things break, developers turn to people—not AI—for help.
- Strong fundamentals set developers apart. Those who understand code deeply are shaping the future of software.
- Python, JavaScript, and HTML/CSS remain dominant. These foundational technologies power most modern software.
- Developers are learning with AI, but they still rely on structured learning for long-term growth.

Unpacking the Survey: Insights into AI, Trust, and Technical Growth
In 2025, artificial intelligence is no longer a novelty for software developers—it’s the norm. According to the latest dev survey from Stack Overflow, which gathered insights from more than 49,000 respondents across 177 countries, AI tools have become a permanent fixture in the daily workflows of developers around the globe.
But the story doesn’t end with rapid adoption. Just beneath the surface, the survey reveals a more nuanced picture: developers are embracing AI, but not uncritically. They’re weighing speed against accuracy, novelty against reliability, and convenience against foundational understanding.
Let’s unpack what the survey tells us, and why the bedrock skills of programming still offer the surest path to adaptability and career resilience in an AI-powered future.
The AI Wave Is Real, but So Is Skepticism
The headline stat is hard to ignore: 84% of developers now use or plan to use AI tools in their workflows, a significant jump from 76% the year before. Even among experienced developers with a decade or more in the industry, nearly 47% use AI tools daily, with another 17% using them weekly.
OpenAI’s GPT models dominate usage, with 81% of developers relying on them. Other models like Anthropic’s Claude Sonnet, Google’s Gemini, and tools from Mistral and Meta are steadily gaining ground. Developers are also exploring more complex integrations, including AI agents—though only 31% currently use them regularly.
Still, trust remains a sticking point. Only 33% of developers say they somewhat trust AI-generated output, and a mere 3% report high levels of trust. That number drops even further among experienced professionals.
Why the Hesitance?
The survey gives a clear answer: while AI often provides a fast starting point, 66% of developers say AI results are “almost right” but not quite—close enough to be tempting, but flawed enough to require time-consuming corrections. 45% say debugging AI-generated code can take longer than writing it from scratch.
In other words, AI is a powerful accelerator, but it can’t replace the foundation.
Fundamentals Still Win
Interestingly, the way developers learn is changing alongside the tools they use. In 2025, over a third of developers taught themselves AI-enabled tools to grow their careers, and 44% learned to code for AI by using AI itself. Instead of only reading textbooks, taking courses, or attending lectures, these developers asked AI tools questions, requested explanations, and generated sample code to study and experiment with. AI tools are increasingly seen not just as helpers, but as teachers.
That said, when asked where they turn to learn, traditional resources still lead: 68% use technical documentation, and 59% rely on online courses.
This balance matters. While AI can teach you how to copy a pattern or generate a quick solution, only structured learning—like stepping through a well-designed HTML/CSS module or writing Python functions from scratch—helps you build long-term mental models of how software works.
It’s the difference between borrowing a ladder and knowing how to build one.
The Risks of Skipping the Basics
The survey makes one thing clear: developers are feeling both the power and the pitfalls of working with AI. When tools hallucinate, miss context, or generate insecure code, developers must rely on their own understanding to catch those mistakes.
Even in 2025, employers still prioritize applicants who know how to build things—not just prompt them into existence.
And that’s where foundational knowledge comes in.
Languages like Python, JavaScript, and HTML/CSS continue to rank among the most widely used and most wanted in 2025. These aren’t just relics of an earlier era—they’re the bedrock upon which AI tools operate.
- Want to spot errors in an AI-generated script? You’ll need to understand the syntax and logic of the language it used.
- Want to build custom apps with AI assistance? You’ll need to grasp how front-end and back-end systems interact.
- Want to troubleshoot unexpected behavior in production code? You can’t fix what you don’t fundamentally understand.
AI can help you write code faster. But learning to code the “old-fashioned” way—through building, testing, and iterating—helps you write it better. That’s a skill set that no model, no matter how powerful, can replace.
Want to Learn the Right Way?
Learning to code with AI tools is powerful—but only when you know what you’re looking at. Start with the fundamentals:
👉 Learn Python the Right Way
👉 Build Web Pages with HTML & CSS
👉 Master JavaScript for Interactive Sites
Developers Still Trust Humans More Than AI
Perhaps the most revealing insight from the 2025 survey is how developers solve problems when AI falls short: When things go wrong, developers trust other developers.
That tells us something essential about the mindset of the modern engineer. AI is seen as a tool—not a colleague, not a replacement, not a magic solution. It can assist, but not guide. It can generate, but not validate. That responsibility still rests on human shoulders.
And for many developers, that’s where job security lives. The value isn’t in writing boilerplate code—it’s in knowing what to build, why it matters, and how to ensure it works.
Future-Proofing Means Going Back to the Roots
At first glance, the 2025 Stack Overflow Developer Survey might suggest that coding itself is becoming optional. But a closer look reveals the opposite: AI is raising the stakes for foundational knowledge.
Because when everyone can generate code with a prompt, what sets you apart is the ability to understand it, evaluate it, and improve it.
That’s why learning Python—a beginner-friendly yet industrial-strength language—is still one of the smartest moves you can make. It’s why JavaScript and HTML/CSS, the pillars of web development, continue to top the “most used” and “most loved” lists year after year.
Foundational courses form the backbone of every AI-powered app, website, or tool you’ll build.
At Treehouse, we’ve seen this firsthand. Students who invest in mastering the fundamentals—through interactive tracks in Python, JavaScript, and front-end development—graduate not just with skills, but with confidence. They’re the ones who use AI tools intelligently, not blindly. They’re the ones debugging faster, building more creatively, and staying relevant in a shifting market.
AI Is the Tool—You Are the Craftsperson
The 2025 Stack Overflow Developer Survey shows us a world in transition. Developers are excited about AI, but not naive. They’re using these tools, but also questioning them. They’re learning with them, but still leaning on human insight.
If there’s one lesson to take from all this, it’s that the strongest developers will be those who combine the best of both worlds—leveraging AI for efficiency, while leaning on foundational coding skills for accuracy, architecture, and creativity.
So whether you’re just starting your journey or returning to the basics, don’t skip the core languages. Learn Python, HTML and CSS, and JavaScript. These are more than lines of code. They’re tools of understanding—and in an age of automation, understanding is the most valuable asset of all.
