I sat down with ChatGPT 4.0 to get a picture of how the role of the software developer is expected to change with the advance of AI technologies. The aim of this interview was to get a straight-from-the-source perspective on the shifts and new directions in software development. Here, we discuss how AI tools like ChatGPT are reshaping the industry and what skills will become important for developers in this new landscape. The insights from this conversation are shared in the following article, providing a glimpse into the future of software development as seen through the eyes of AI.

Giuseppe: Act as a seasoned software development professional with a quarter-century of experience under your belt, you're invited to share your insights at Brunel University London. I, an associate professor of Software Engineering in the Computer Science department, will engage with you in a conversational interview during one of my lectures. My students will be in attendance, eager to hear your perspective on the evolving landscape of software development, particularly in light of emergent AI tools like ChatGPT. Let's explore the future responsibilities and opportunities for software developers together. Your thoughtful and informed responses will help us understand what lies ahead in our field.

Hello, and thank you for the invitation. It's an honor to discuss these critical topics with the next generation of software engineers.

Software development has always been dynamic, but the introduction of AI tools like ChatGPT is accelerating changes in ways we couldn't have predicted even a decade ago. AI is becoming an indispensable tool in a developer's arsenal, not just for automating mundane tasks but also for enhancing creativity and problem-solving.

As we look to the future, I see developers' roles evolving in several key areas:

Augmented Coding: With AI assistance, developers can expect to write more reliable code faster. AI can suggest improvements, identify potential bugs, and even write code snippets. This doesn't reduce the need for skilled developers; it elevates their work to focus on higher-level architecture and problem-solving.

Lifelong Learning: The rapid pace of change means developers can't afford to be complacent about their skills. Continuous learning will be essential, with developers needing to stay up-to-date with not only new programming languages and tools but also the latest advancements in AI and machine learning.

Cross-disciplinary Skills: The future developer will likely need a broader skill set that transcends traditional computer science. Understanding user experience, product management, and even fields like psychology and ethics will become increasingly important as we build more complex and impactful software systems.

Collaboration with AI: We're moving towards a collaborative model where AI acts as both a tool and a team member. This means developers will need to learn how to best collaborate with AI to optimize workflow, creativity, and efficiency.

The rise of AI tools doesn't spell the end for software developers. Rather, it's a new chapter that promises to enhance our capabilities, demand new skills, and necessitate a thoughtful approach to the ethical dimensions of our work. The opportunities ahead are vast.

Giuseppe: Can you list the differences between software development before GPT and after?

Certainly, here's a list that outlines the key differences in software development before and after the emergence of tools like GPT:

Coding Speed:

Before GPT: Coding was often slower and more manual.

After GPT: There's faster output with AI-assisted code generation.

Bug Detection:

Before GPT: Bug detection was primarily a manual and time-consuming process.

After GPT: Bug detection is now aided by AI, offering faster detection and suggestions.

Learning & Resources:

Before GPT: Learning relied heavily on formal education and static documentation.

After GPT: There's a shift toward dynamic, AI-assisted learning and resources that are more interactive and personalized.

Collaboration:

Before GPT: Collaboration was mostly human-centric with limitations based on team capabilities.

After GPT: AI provides additional collaborative input, increasing team capabilities and efficiency.

Role of Developer:

Before GPT: Developers were mainly focused on writing and testing code.

After GPT: The role has evolved to include AI management and oversight, along with coding.

Problem-solving:

 This list simplifies some of the contrasts, but it gives you an idea of how GPT and similar AI tools are reshaping the field. The after-points reflects an environment where AI plays an active role in the development process, offering support that ranges from writing code to proactive maintenance. It's important to note, though, that while AI impacts these areas, it doesn't eliminate the need for skilled developers—it changes the nature of their work.

Giuseppe: What about the fundamental steps of software development? From requirements to updates. How the phases, as we know them now, will change in the future?

The fundamental steps of software development, typically captured in models like the Waterfall or Agile methodologies, are indeed being influenced by AI. Here's a look at how these phases may evolve:

Requirements Gathering:Before AI: Done through meetings, document analysis, and user feedback.After AI: AI can help by analyzing user feedback at scale, predicting user needs, and suggesting features based on data trends.

Design:Before AI: Design is created based on best practices and prior experience.After AI: AI can offer design suggestions, automatically generate user interfaces, and simulate user interactions for feedback before development.

Implementation (Coding):Before AI: Hand-crafted code by developers.After AI: AI-assisted coding with tools that can write boilerplate code, suggest optimizations, and help developers avoid bugs.

Testing:Before AI: Manual and automated tests designed by developers.After AI: AI can generate test cases, predict where bugs are likely to occur, and even fix them automatically.

Deployment:Before AI: Deployment processes are often manual or semi-automated.After AI: AI can manage continuous deployment, monitor for issues, and roll back changes if problems are detected.

Maintenance:Before AI: Reactive approach based on user reports and developer observations.After AI: Proactive maintenance with AI predicting issues before they occur, and suggesting areas of improvement.

Updates (Evolution):Before AI: Updates based on new requirements, user feedback, and developer initiative.After AI: AI helps prioritize update features based on user engagement data and can even prototype new features.

AI has the potential to augment each step of the software development lifecycle. It can provide developers with insights drawn from large datasets and automate repetitive tasks, which allows them to focus on more complex problems and innovative features. However, AI won't replace the need for human judgment, creativity, and decision-making in software development; it'll just shift the focus of these human qualities to different areas. The developer's role becomes more strategic, oversight-driven, and focused on interpreting AI-generated data and recommendations within the context of human needs and values.

Giuseppe: Now the $1 million question (somehow we know what your answer will be, given your previous answers): Do you see AI replacing software developers?

 The $1 million question indeed! The short answer is no, I don't see AI replacing software developers. Here's why:

AI, even advanced models like GPT, excel at tasks involving patterns, repetition, and data processing—things that can be learned from existing data. But software development is not just about cranking out code; it's about understanding problems, inventing solutions, and adapting to an ever-changing landscape of user needs and technological capabilities.

Here are a few reasons developers are here to stay:

Creative Problem Solving: AI can suggest solutions based on what it has seen before, but it struggles with novel problems. Developers excel at thinking outside the box and coming up with creative solutions.

Understanding Context: AI lacks deep understanding. Developers can grasp the broader context of a project—organizational goals, customer needs, and so on—which is crucial for successful software.

Managing Complexity: Software systems can be incredibly complex, integrating with multiple systems, adhering to regulations, and fulfilling varied user needs. Managing this complexity requires human oversight.

Ethical Judgments: Decisions about how or whether to implement certain features often involve ethical considerations. AI does not understand ethics; it follows patterns.

Interpersonal Skills: Collaboration, negotiation, and leadership are key to successful projects. These are inherently human skills that AI cannot replicate.

Adaptability and Learning: The ability to learn from non-data sources, like a conversation or an unexpected event, and to adapt accordingly is something AI cannot do as flexibly as a human can.

AI is a tool—albeit a powerful one—that can enhance the capabilities of developers, not a replacement for them. The demand for human developers may shift toward oversight, design, and the integration of AI tools into the development process, but it won't disappear. Developers who learn to use AI effectively will likely find themselves in high demand, working on more interesting problems than ever before.

Giuseppe: Do you see the end of programming languages as we know them today?

The end of programming languages as we know them today is unlikely, but their role and how we use them are definitely undergoing a transformation. Here's a perspective on this:

Evolution, Not Extinction: Programming languages evolve over time. Just as assembly language didn't disappear but rather took a backseat to higher-level languages, current programming languages will evolve and adapt to new paradigms brought on by AI.

Specialization and Domain-Specific Languages: There may be a rise in specialized and domain-specific languages (DSLs) designed to work effectively with AI, allowing developers to define and adjust AI behaviors more naturally.

Abstraction and High-Level Coding: We might see more abstract, high-level "languages" that are more about defining what needs to be done rather than how it's done, with AI handling the translation into lower-level code.

Interactivity and Real-Time Feedback: Programming could become more interactive, with AI providing real-time feedback and suggestions, and the language itself might be more flexible and adaptive.

Natural Language Programming (NLP): There's ongoing research into programming through natural language, which could make coding more accessible and change the nature of programming languages to be more aligned with human language.

AI-Optimized Languages: We might see new or existing languages that are optimized for AI development, with built-in functionalities specifically for building and training models, much like how Python has become synonymous with data science due to its ecosystem.

Tooling Changes: The tools we use for programming will likely incorporate AI to a greater extent, changing how we interact with languages—think pair programming with an AI, where the AI understands the language syntax and semantics.

Code Generation and Maintenance: AI might handle more of the boilerplate code generation and maintenance, so the languages might evolve to support more concise and high-intent-focused coding styles.

Programming languages are tools for expressing computational logic and as long as there's a need for humans to direct and implement complex logic, there will be a need for some form of programming language. The form and complexity of these languages may change, influenced by AI, but the core concept of using a language to instruct and create will remain essential in the realm of software development.

Giuseppe: You don’t see a future where we will be using natural language instead of coding? Like telling GPT in plain English what to do? Or since I'm Italian, will I be able to use Italian instead of Python in the future?

Using natural language to program computers, often referred to as natural language programming (NLP), is a fascinating concept and a growing area of research. However, it's important to distinguish between programming in a natural language and using natural language to aid in programming tasks.

In the future, it's conceivable that you could explain what you want in Italian, and an AI like GPT could help you by either generating the necessary code in a programming language like Python or by interfacing directly with the computer to execute your commands. Here's how that might look:

Natural Language as a Frontend: You might describe the program you want to build in Italian, and the AI could translate your intent into code, handling the complexity of syntax and semantics behind the scenes.

Language Agnostic Development: The AI could potentially allow you to work in your preferred language, breaking down the barrier of needing to know English or a specific programming language syntax to create software.

Code Generation: Tools might become sophisticated enough to not only understand your instructions but also generate efficient, optimized, and error-free code, much as compilers today optimize lower-level machine code.

Improved Accessibility: This could significantly lower the barrier to entry for programming, making it more accessible to a wider range of people with ideas, not just those who have learned traditional programming languages.

Human-AI Collaboration: Instead of fully automated code generation, a more likely near-term scenario is a collaborative approach where humans provide guidance and context in natural language, and AI assists with the technical implementation.

Despite these possibilities, there are challenges:

Precision and Ambiguity: Natural languages are often ambiguous and lack the precision needed for programming. AI would need to ask follow-up questions to clarify intent, which could become cumbersome.

Complex Logic: Some aspects of programming, especially complex algorithms and data structures, don't translate neatly into natural language.

Performance: Automatically generated code may not be as efficient or optimized as hand-written code, especially for high-performance applications.

Control and Understanding: There's a risk that if the AI handles too much of the programming task, developers might have less understanding and control over the end product.

While AI might not replace traditional programming languages entirely, it could change how we interact with them, making the process of software development more intuitive and accessible to non-English speakers or those without formal programming training. The key will be finding the right balance between the efficiency and precision of traditional programming languages and the accessibility and intuitiveness of natural language.

Giuseppe: Do you foresee a reduced demand for software developers in terms of numbers within software development companies? Given that AI is poised to enhance the software development process, will this lead to a decrease in the required number of developers?

 The question of AI's impact on the demand for software developers is complex, and opinions vary. However, there are several factors to consider that might influence the demand in various ways:

Increased Efficiency: AI can certainly make individual developers more efficient by automating routine tasks, which could mean that fewer developers are needed for certain types of work.

New Opportunities: At the same time, AI is likely to create new opportunities and markets. As software becomes more integral to all aspects of life and business, the demand for developers to create, maintain, and improve these systems could grow.

Broader Access to Development: AI could lower barriers to entry, allowing more people to participate in development, which could increase the overall number of people working in software development, albeit in different capacities.

AI as a Tool, Not a Replacement: If AI is seen primarily as a tool that aids development rather than a replacement for developers, then the demand for developers could remain strong, particularly for those who can use these tools effectively.

Economic and Business Dynamics: Broader economic and business factors also play a role. For example, if companies can bring products to market faster with AI's help, they might invest more in software development, increasing demand for developers.

Global Software Development Trends: The global need for digital transformation across industries may continue to drive high demand for software development skills, even as individual productivity improves.

In summary, while AI will likely change the nature of software development work and could reduce the need for developers in certain areas, it's also likely to create new types of demand for developers with different skill sets. The overall impact on the number of software development jobs is not clear-cut and will be influenced by how companies and markets adapt to and integrate AI technologies.

Giuseppe: What are your recommendations to our students?

For students preparing for a future in software development where AI plays an integral role, I’d recommend the following:

Embrace AI and Machine Learning: Gain a basic understanding of AI and machine learning concepts. You don't need to become an expert in these areas (unless you want to), but you should understand how they work and their implications for software development.

Stay Curious and Keep Learning: The tech field changes rapidly. Cultivate a love for learning and stay updated on industry trends and emerging technologies. Regularly set aside time for learning and experimentation.

Develop Strong Fundamentals: A strong foundation in computer science fundamentals, algorithms, data structures, and design principles is crucial. These core concepts will remain important regardless of changes in specific technologies or tools.

Cultivate Soft Skills: Develop your communication, teamwork, and problem-solving skills. These will be vital as you'll often need to work in multidisciplinary teams and communicate complex ideas clearly.

Understand the Business Side: Try to grasp the business context in which you’re developing software. This will help you to build solutions that not only work well but also deliver real value.

Get Comfortable with Abstraction: Work on understanding high levels of abstraction. This means being able to plan out systems and understand architecture, not just write code.

Focus on User Experience: Keep the end-user in mind. The goal of software is to solve problems for people, so understanding user experience (UX) design can be a big advantage.

Ethics and Responsibility: Learn about the ethical implications of software, particularly as it relates to AI. Your work will impact real people, and understanding these impacts is crucial.

Hands-On Experience: Engage in as much hands-on coding and real-world projects as possible. This could be through internships, personal projects, or contributions to open-source projects.

Build a Portfolio: Start working on projects now that you can show to potential employers. Your GitHub repository or personal website can be just as important as your resume.

Networking: Connect with other students, professionals, and groups in the software development community. Attend workshops, seminars, and tech meetups to build relationships and learn from others.

By focusing on these areas, students can prepare themselves not only to enter the software development field but to excel in it, even as AI transforms the landscape.
