Why Aspiring Developers Still Need to Learn Object-Oriented Programming

Dr. Kai Dupe • October 3, 2025

Object-oriented programming, at its core, is about modeling software systems around “objects” that represent real-world entities

In today’s fast-moving world of software development, it might seem tempting to skip over traditional programming paradigms like object-oriented programming (OOP) and head straight into newer trends like functional programming, data-driven frameworks, or AI tooling. However, OOP continues to be a critical skill that aspiring software developers should master.

Object-oriented programming, at its core, is about modeling software systems around “objects” that represent real-world entities. This approach, which emphasizes encapsulation, abstraction, inheritance, and polymorphism, has been the foundation of most enterprise applications for decades. Whether you are working in Java, C++, C#, or Python, OOP principles show up everywhere. Even if you never create your own elaborate class hierarchies, understanding how objects interact is key to working with frameworks, libraries, and APIs that dominate modern development.

One of the main reasons OOP remains important is that it teaches developers how to think about software design. It enforces structure and modularity, making systems easier to maintain and scale. For instance, when designing a large application like an e-commerce platform, OOP concepts help developers break down the system into manageable components: products, users, orders, and payment modules. Each of these components can evolve independently while still interacting through well-defined interfaces.

OOP also supports the collaborative nature of modern software development. Teams can work on different parts of the codebase with minimal overlap, which is essential for building complex systems across industries such as finance, healthcare, and education.

Even experts in programming education recognize its enduring relevance. In his book Code Complete, Steve McConnell emphasizes that, Good object-oriented design makes code more understandable, more maintainable, and less error prone. This insight highlights why OOP continues to be taught in nearly every computer science curriculum — it fosters long-term skills that apply regardless of language or framework.

Of course, OOP is not the only paradigm developers need to know. Functional programming, declarative approaches, and event-driven systems are all valuable tools. But a strong grounding in OOP provides a solid mental model that makes it easier to pick up these other paradigms later.

For aspiring developers, the message is clear: learn OOP, master its principles, and then branch out. OOP may not dominate every cutting-edge domain, but it is still a cornerstone of professional software development — and will continue to be for years to come.

Stepping onto the campus of Morehouse College this past weekend for Admitted Students Day was more than a visit—it was a moment of reflection. As I watched young Black men walk with purpose across the yard, I found myself asking a simple but profound question: What would it have been like for me to study computer science here? My journey into computing was shaped in environments where I was often the only Black man in the room. That reality brings with it an unspoken weight—the need to prove you belong, the awareness of being watched, and sometimes, the quiet isolation that comes with underrepresentation. Standing at Morehouse, I realized that this burden is not a given. It is a condition of the environment. At Morehouse, the environment is different by design. Here, Black men are not anomalies—they are the standard. I imagined what it would feel like to learn algorithms, data structures, and software development in a space where my identity was not questioned but affirmed. Where excellence is expected, not in spite of who you are, but because of it. As a computer science professor, I understand the academic rigor required to succeed in this field. There is no shortcut through recursion, no bypass around debugging, no substitute for disciplined problem-solving. But what struck me during my visit is how much context matters. When students are free from the psychological burden of proving they belong, they can redirect that energy toward mastering the material. They can collaborate more openly, ask questions more freely, and take intellectual risks without fear. I also thought about legacy. At Morehouse, students walk the same grounds as Martin Luther King Jr.. That kind of history does something to a person. It raises the bar—not just academically, but personally. It invites students to see their education not just as a pathway to a career, but as preparation for impact. Leaving campus, I felt inspired—but also reflective. I cannot rewrite my journey, but I can appreciate what spaces like Morehouse offer the next generation. For a Black male pursuing computer science, it is more than a degree. It is an opportunity to develop skill, confidence, and identity in alignment. And that combination is powerful.

If you walk into most computer science classrooms today, you might assume that computing has always been a male-dominated field. As someone who has spent decades in the industry and now teaches the next generation of developers, I can tell you—that assumption is not only common, it’s historically inaccurate. In the early days of computing, many of the first programmers were women. Ada Lovelace is widely recognized as the first computer programmer, having written what we would now call an algorithm for Charles Babbage’s Analytical Engine. Fast forward to the 1940s, and women were programming some of the first electronic computers, including ENIAC. These were not peripheral roles. These women were solving complex computational problems, often inventing programming techniques as they went (Abbate, 2012). So what happened? From a systems perspective, the answer is not mysterious—it’s structural. In its early stages, programming was considered clerical work. It required precision, patience, and attention to detail—qualities that, at the time, were socially assigned to women. But as computing became more central to business, government, and innovation, its status changed. What was once seen as routine work became prestigious and lucrative. And when that shift happened, the demographics shifted with it. By the 1980s, we see a clear inflection point. Personal computers entered the home—but they were marketed primarily to boys. This created an early access gap that translated into confidence, experience, and eventually career pathways. At the same time, hiring practices and workplace cultures began to favor men, reinforcing a feedback loop that pushed women out of the field (Hicks, 2017). Over time, the narrative changed. Computing was no longer something women had built—it became something they were seen as entering late. But that narrative is not just incomplete—it’s a distortion. Understanding this history is not about nostalgia; it’s about accuracy. When students learn that women were foundational to computing, it reshapes how they think about the field. Diversity is no longer framed as a modern intervention—it is recognized as part of computing’s original DNA. In my classroom, I’ve seen what happens when students encounter this truth. It disrupts assumptions. It broadens participation. And perhaps most importantly, it changes who students believe belongs in this space. So, if women were the original programmers, what happened? Part of the answer lies in systems—education, marketing, hiring, and culture. But another part lies in storytelling. The stories we tell about computing shape who feels invited to participate in it. As educators, technologists, and leaders, we have an opportunity—and a responsibility—to tell that story more accurately. References Abbate, J. (2012).

During Women's History Month, we often celebrate women who have made groundbreaking contributions to science and technology. What many people do not realize, however, is that in the earliest years of the computing industry, programming was largely done by women. This overlooked chapter of history reveals how deeply women helped shape modern computing—and how cultural shifts later obscured their contributions. One of the most famous examples comes from the development of the ENIAC, one of the first general-purpose electronic computers built during World War II. When the machine was unveiled in 1946, public attention focused primarily on the hardware and the male engineers who built it. Yet the individuals responsible for programming the computer were six women mathematicians: Jean Bartik, Kathleen McNulty, Betty Jennings, Frances Bilas, Ruth Lichterman, and Marlyn Wescoff. Their work was extraordinarily complex. Programming ENIAC did not involve writing code in a modern programming language. Instead, they programmed the machine by rewiring plugboards, configuring switches, and designing logical sequences of operations to compute ballistic trajectories for the U.S. military. In effect, they were inventing the practice of programming as they went along. Despite the significance of their work, these women were largely left out of the early historical record. Photographs from the ENIAC project sometimes showed them standing beside the machine, but they were often misidentified as models rather than as the programmers who made the system function. For decades, their contributions were largely forgotten. Women continued to play critical roles in computing in the years that followed. One notable figure was Grace Hopper, who helped develop one of the first compilers and contributed to the development of the programming language COBOL. Her work helped transform programming from a hardware-focused task into the software-driven discipline we know today. Ironically, programming was not initially considered a prestigious profession. In the early decades of computing, it was sometimes viewed as routine clerical work, and organizations often hired women to perform it. However, as software became more central to the technology industry in the 1960s and 1970s, the status of programming began to change. Companies started redefining the role as a highly technical and prestigious occupation. At the same time, hiring practices began emphasizing personality profiles and educational pathways that favored men, while early home computers were heavily marketed to boys. These cultural and institutional shifts gradually pushed many women out of the field. By the 1980s, computer science programs had become overwhelmingly male-dominated, creating the demographic pattern that still exists in much of the technology industry today. Understanding this history reminds us that the gender imbalance in computing is not inevitable or inherent to the field. Women were present at the very beginning of modern computing and were instrumental in building the foundations of programming itself. For readers interested in learning more, two excellent resources are Recoding Gender by Janet Abbate, which examines the historical role of women in computing, and Broad Band by Claire L. Evans, a narrative history of women’s contributions to the development of the internet and computing culture.

For those of us who have spent decades working in technology, it is easy to forget how different the industry looked thirty years ago. When I began my career, the tech world was rapidly expanding, but it was also strikingly narrow in who it included. Conversations about equity, representation, and access were often peripheral — if they happened at all. That is why the work of Rev. Jesse Jackson in Silicon Valley stands out to me, not just as a moment in civil rights history, but as a turning point in the culture of technology itself. Many people know Jesse Jackson for his role in the Civil Rights Movement, but fewer recognize how intentionally he turned his attention toward the tech industry. He understood something early that many of us working in the field were only beginning to realize: technology would shape the future economy. If entire communities were excluded from participation in tech, they would be excluded from opportunity, wealth, and influence in the decades ahead. Jackson’s approach was practical and strategic. He challenged major technology companies to release diversity data at a time when transparency was uncommon. As someone who has watched the industry evolve over three decades, I can say that this push mattered. Today, annual diversity reports are routine, and companies are expected to discuss representation openly. That shift toward accountability did not happen by accident — it came from sustained public pressure and advocacy. What impressed me most about his work was that he framed equity as more than a hiring issue. He emphasized supplier diversity, entrepreneurship, and access to capital, arguing that inclusion meant participation in the entire technology ecosystem. That perspective resonates deeply with me as both a technologist and an educator. I have seen firsthand how access to networks, mentorship, and opportunity often matters just as much as technical skill. The ripple effects of that advocacy are visible today. Conversations about ethical AI, algorithmic bias, and inclusive design reflect a growing understanding that technology is shaped by the people who build it. As someone who has worked through multiple generations of technological change — from early software development practices to cloud computing and now AI — I can say with confidence that the industry now recognizes diversity not only as a social responsibility but as a driver of innovation. Of course, progress is not linear. The tech industry continues to wrestle with questions of equity, and current debates around DEI show that the work is far from finished. Yet the fact that these conversations are central rather than marginal is itself part of Jackson’s legacy. From my vantage point after thirty years in technology, I see Jesse Jackson’s Silicon Valley work as a bridge between the civil rights struggles of the past and the innovation challenges of the future. He reminded the industry that technology is not just about code or products — it is about people, access, and who gets to help shape the world we are building together.

The field of computing is often portrayed as a neutral, merit-based domain driven solely by innovation and technical brilliance. Yet this narrative obscures a critical truth: the systematic omission of Black contributions from computing history has materially shaped who feels welcome, visible, and valued in the field today. The underrepresentation of African Americans in computing is not an accident of interest or aptitude—it is the cumulative result of historical erasure, structural barriers, and distorted storytelling. Factor 1: Historical Erasure from Canonical Narratives Black technologists played foundational roles in early computing—as mathematicians, programmers, systems architects, and trainers—yet their work has been routinely excluded from textbooks, curricula, and popular histories. As documented in Hidden Figures by Margot Lee Shetterly, Black women were essential to NASA’s computational breakthroughs, but their contributions remained invisible for decades. This erasure sends a powerful signal: computing is framed as a space where Black excellence is anomalous rather than foundational. Factor 2: Structural Barriers to Access and Credentialing Beyond storytelling, African Americans were systematically excluded from the institutions that conferred legitimacy in computing—elite universities, corporate research labs, and early tech firms. Historian Joy Lisi Rankin documents how access to early computer systems was tightly controlled, favoring already-privileged institutions and populations. Even when Black technologists contributed, intellectual credit and ownership often flowed elsewhere. Factor 3: The Myth of the Lone Genius Technologist Dominant computing narratives emphasize individual genius—often white and male—while minimizing collaborative and community-based labor. Scholar Ruha Benjamin argues that these narratives reinforce racial hierarchies by defining innovation narrowly and excluding socially grounded forms of technical expertise. Conclusion The underrepresentation of African Americans in computing cannot be solved by recruitment alone. It requires historical repair—restoring omitted contributions, reframing who computing is for, and teaching students that Black people have always been builders of digital futures.

Every few years, the tech industry reinvents itself. New tools appear, old practices fade, and entire job roles evolve. As we move toward 2026, one thing is clear: the definition of “software developer” is expanding. Writing code is still essential — but today’s successful developers must also think like system architects, security analysts, automation engineers, and lifelong learners. At the top of the priority list is AI-driven development . Artificial intelligence is no longer just a feature inside applications; it is becoming a core collaborator in the development process. Tools like GitHub Copilot and large language models are reshaping how code is written, tested, and maintained. Aspiring developers should focus on learning how to integrate AI into workflows, design prompts effectively, and understand how these systems generate and evaluate code. Those who treat AI as a productivity partner — rather than a shortcut — will move faster and build better software. Equally important is cloud and automation fluency . In 2026, nearly every serious application will be cloud-based. Developers must be comfortable working with platforms such as AWS, Azure, or Google Cloud, and understand cloud-native design: microservices, serverless computing, containerization, and continuous integration pipelines. Automation is now part of the developer’s job description. Knowing how to deploy, monitor, and scale software is just as important as writing it. With this growing complexity comes increased risk, making cybersecurity and secure coding non-negotiable. Modern developers must think about security from the first line of code: managing credentials, protecting APIs, preventing injection attacks, and integrating security checks into development pipelines. Security literacy will increasingly separate entry-level developers from trusted professionals. Yet for all the new tools and trends, strong fundamentals remain the backbone of the profession. Algorithms, data structures, debugging, and system design still determine whether software performs well, scales, and remains maintainable. AI may generate code, but it cannot replace sound engineering judgment. Finally, the developers who thrive in 2026 will possess exceptional human skills: communication, collaboration, adaptability, and curiosity. Technology evolves too quickly for any single skillset to last a career. The most valuable developers are those who learn continuously and translate complex technical ideas into real business solutions. The future of software development isn’t about chasing every new trend — it’s about building a resilient foundation and learning how to evolve with the industry. That’s the real competitive advantage.

One of the biggest misconceptions students have about software development is believing that learning a programming language is the finish line. It’s not. In reality, languages are just one piece of a much larger ecosystem known as the developer toolchain—and employers expect graduates to understand that ecosystem on day one. In industry, software is rarely written in isolation. Developers collaborate, experiment, break things, fix them, test constantly, and deploy incrementally. None of that works without tools. Version control systems like Git allow teams to work safely in parallel. Platforms like GitHub provide structure for collaboration, feedback, and accountability. These tools are not optional add-ons; they are the foundation of professional software development. Equally important is proficiency with an IDE such as Visual Studio Code. A modern IDE is more than a text editor—it is a thinking environment. Debuggers, code navigation, and refactoring tools help developers reason about complex systems and fix problems efficiently. Students who rely solely on print statements quickly hit a ceiling when projects grow beyond a few hundred lines. Command-line skills are another quiet differentiator. While graphical tools are convenient, many professional workflows—build systems, servers, automation, and cloud deployments—live in the terminal. Comfort at the command line signals independence and readiness for real-world environments. Today’s toolchain is also evolving. Containers like Docker have changed how software is packaged and deployed, while AI tools such as GitHub Copilot are reshaping how code is written and reviewed. The goal is not to let AI replace thinking, but to learn how to evaluate, guide, and improve AI-generated output—an essential skill for modern developers. For students, the takeaway is simple: languages get you started; tools make you effective. Mastering the developer toolchain builds confidence, supports collaboration, and prepares you not just to write code, but to work as a software developer.
