Hard and soft skills for developers coding in the age of AI
3/14/2024
Donate While AI revolutionizes software development, it still relies on developers to pilot its use. In this blog, we’ll cover the skills that developers need to have for navigating this new AI-powered coding frontier.
As AI continues to shape the development landscape, developers are navigating a new frontier—not one that will make their careers obsolete, but one that will require their skills and instincts more than ever.
Sure, AI is revolutionizing software development, but that revolution ultimately starts and stops with developers. That’s because these tools need to have a pilot in control. While they can improve the time to code and ship, they can’t serve as a replacement for human oversight and coding abilities.
We recently conducted research into the evolving relationship between developers and AI tools and found that AI has the potential to alleviate the cognitive burden of complex tasks for developers. Instead of being used solely as a second pair of hands, AI tools can also be used more like a second brain, helping developers be more well-rounded and efficient.
In essence, AI can reduce mental strain so that developers can focus on anything from learning a new language to creating high-quality solutions for complex problems. So, if you’re sitting here wondering if you should learn how to code or how AI fits into your current coding career, we’re here to tell you what you need to know about your work in the age of AI.
A breif history of AI Powered Technology
While the media buzz around generative AI is relatively new, AI coding tools have been around —in some form or another—much longer than you might expect. To get you up to speed, here’s a brief timeline of the AI-powered tools and techniques that have paved the way for the sophisticated coding tools we have today:
1950s: Autocoder was one of the earliest attempts at automatic coding. Developed in the 1950s by IBM, Autocoder translated symbolic language into machine code, streamlining programming tasks for early computers.
1958: LISP, one of the oldest high-level programming languages created by John McCarthy, introduced symbolic processing and recursive functions, laying the groundwork for AI programming. Its flexibility and expressive power made it a popular choice for AI research and development.
1970: SHRDLU, developed by Terry Winograd at MIT, was an early natural language understanding program that could interpret and respond to commands in a restricted subset of English, and demonstrated the potential for AI to understand and generate human language.
1980s: In the 1980s, code generators, such as The Last One, emerged as tools that could automatically generate code based on user specifications or predefined templates. While not strictly AI-powered in the modern sense, they laid the foundation for later advancements in code generation and automation.
1990s: Neural network–based predictive models were increasingly applied to code-related tasks, such as predicting program behavior, detecting software defects, and analyzing code quality. These models leveraged the pattern recognition capabilities of neural networks to learn from code examples and make predictions.
2000s: Refactoring tools with AI capabilities began to emerge in the 2000s, offering automated assistance for restructuring and improving code without changing its external behavior. These tools used AI techniques to analyze code patterns, identify opportunities for refactoring, and suggest appropriate refactorings to developers.
These early AI-powered coding tools helped shape the evolution of software development and set the stage for today’s AI-driven coding assistance and automation tools, which continue to evolve seemingly every day.
Evolving beyond the IDE
Initially, AI tools were primarily confined to the integrated development environment (IDE), aiding developers in writing and refining code. But now, we’re starting to see AI touch every part of the software development lifecycle (SDLC), which we’ve found can increase productivity, streamline collaboration, and accelerate innovation for engineering teams.
In a 2023 survey of 500 U.S.-based developers, 70% reported experiencing significant advantages in their work, while over 80% said these tools will foster greater collaboration within their teams. Additionally, our research revealed that developers, on average, complete tasks up to 55% faster when using AI coding tools.
Here’s a quick look at where modern AI-powered coding tools are and some of the technical benefits they provide today:
Code completion and suggestions. Tools like GitHub Copilot use large language models (LLMs) to analyze code context and generate suggestions to make coding more efficient. Developers can now experience a notable boost in productivity as AI can suggest entire lines of code based on the context and patterns learned from developers’ code repositories, rather than just the code in the editor. Copilot also leverages the vast amount of open-source code available on GitHub to enhance its understanding of various programming languages, frameworks, and libraries, to provide developers with valuable code suggestions.
Generative AI in your repositories. Developers can use tools like GitHub Copilot Chat to ask questions and gain a deeper understanding of their code base in real time. With AI gathering context of legacy code and processes within your repositories, GitHub Copilot Enterprise can help maintain consistency and best practices across an organization’s codebase when suggesting solutions.
Natural language processing (NLP). AI has recently made great strides in understanding and generating code from natural language prompts. Think of tools like ChatGPT where developers can describe their intent in plain language, and the AI produces valuable outputs, such as executable code or explanations for that code functionality.
Enhanced debugging with AI. These tools can analyze code for potential errors, offering possible fixes by leveraging historical data and patterns to identify and address bugs more effectively.
To implement AI tools, developers need technical skills and soft skills
There are two different subsets of skills that can help developers as they begin to incorporate AI tools into their development workflows: technical skills and soft skills. Having both technical chops and people skills is super important for developers when they’re diving into AI projects—they need to know their technical skills to make those AI tools work to their advantage, but they also need to be able to work well with others, solve problems creatively, and understand the big picture to make sure the solutions they come up with actually hit the mark for the folks using them.
Let’s take a look at those technical skills first.
Getting technical
Prompt engineering
Prompt engineering involves crafting well-designed prompts or instructions that guide the behavior of AI models to produce desired outputs or responses. It can be pretty frustrating when AI-powered coding assistants don’t generate a valuable output, but that can often be quickly remedied by adjusting how you communicate with the AI. Here are some things to keep in mind when crafting natural language prompts:
Be clear and specific. Craft direct and contextually relevant prompts to guide AI models more effectively.
Experiment and iterate. Try out various prompt variations and iterate based on the outputs you receive.
Validate, validate, validate. Similar to how you would inspect code written by a colleague, it’s crucial to consistently evaluate, analyze, and verify code generated by AI algorithms.
Testing and security
With AI’s capabilities, developers can now generate and automate tests with ease, making their testing responsibilities less manual and more strategic. To ensure that the AI-generated tests cover critical functionality, edge cases, and potential vulnerabilities effectively, developers will need a strong foundational knowledge of programming skills, testing principles, and security best practices. This way, they’ll be able to interpret and analyze the generated tests effectively, identify potential limitations or biases in the generated tests, and augment with manual tests as necessary.
Here’s a few steps you can take to assess the quality and reliability of AI-generated tests:
Verify test assertions. Check if the assertions made by the AI-generated tests are verifiable and if they align with the expected behavior of the software.
Assess test completeness. Evaluate if the AI-generated tests cover all relevant scenarios and edge cases and identify any gaps or areas where additional testing may be required to achieve full coverage.
Identify limitations and biases. Consider factors such as data bias, algorithmic biases, and limitations of the AI model used for test generation.
Evaluate results. Investigate any test failures or anomalies to determine their root causes and implications for the software.
