AI-Assisted Coding: New Google Research Says How You Should Use It

5/5 - (3 votes)

As the landscape of technology and machine learning evolves, we’re witnessing a paradigm shift in the field of software development.

The advent of AI-powered code-writing assistants, like Github’s Copilot, Alphabet’s DeepMind’s AlphaCode, and Amazon’s CodeWhisperer, is revolutionizing the traditional practice of writing code and molding new development workflows.

This Finxter article based on a new Google Research Paper probes deeper into these trends, exploring the impact of code writing assistants, and the changing dynamics they introduce into the world of coding.

The AI Revolution in Code Generation

The assistance of AI in coding is not just about automating mundane tasks; it’s about enhancing the efficiency and productivity of software developers. It aims to reduce developer workloads, curtail task completion times, and mitigate human errors.

But are these tools as effective as they claim? Can they truly enhance the way engineers write code?

Emerging research suggests that developers interact with these AI assistants in two significant modes: acceleration and exploration.

  • In the acceleration mode, developers use AI assistance to expedite planned actions, while
  • in the exploration mode, the focus shifts to planning next steps and exploring possible paths forward.

Interestingly, studies suggest that the coding process is evolving towards a review-centric model due to these AI tools:

The Efficacy of AI in Coding: Metrics and Measurements

Understanding the efficacy of these code-writing assistants requires a holistic approach, combining both behavioral metrics and attitudinal measures.

On one hand, behavioral metrics, such as daily completions per user (DCPU), coding iteration time, and the percentage of new code generated from accepting ML code completion suggestions, provide feedback on the performance of the AI model.

On the other hand, attitudinal measures help gauge user sentiment, such as perceived utility and productivity.

Surprisingly, developers reportedly feel more productive when using AI-based assistance, even if they aren’t always faster at producing code. This presents a paradox: while AI assists in coding, it doesn’t necessarily translate into faster code production.

Ten Ways to Use AI-Assisted Coding as a Developer

  1. Code Completions: One of the key uses of AI-assisted coding is through intelligent code completions. As you type code, these tools can predict and suggest the next few lines, saving you keystrokes and making your coding more efficient.
  2. Bug Detection: AI-assisted tools can use machine learning algorithms to analyze your code as you write, helping to predict and identify potential bugs, errors, or inefficiencies before they cause problems.
  3. Code Refactoring: AI tools can suggest better or more efficient ways to structure your code. By learning from a vast amount of high-quality, open-source code, these tools can provide recommendations on how to refactor your code for better performance or readability.
  4. Code Documentation: Some AI-assisted coding tools can auto-generate comments or documentation for your code. This not only saves time but can also make your code easier to understand for others (and for yourself in the future).
  5. Semantic Code Search: AI can help in semantic code search where you can search code snippets based on functionality rather than exact keyword matches. This could be particularly useful when looking for a specific function or method implementation.
  6. Code Translation: If you need to convert code from one language to another, some AI tools can assist with this. This can be particularly useful if you need to migrate a project to a new language.
  7. Automated Testing: AI can help generate unit tests based on your code, saving you time and helping ensure that your code is robust and behaves as expected.
  8. Learning New Languages: AI-assisted coding can provide guidance when you’re learning a new programming language. By suggesting completions, it allows you to learn syntax and idioms in a hands-on manner.
  9. Code Review: Some AI tools can assist in code review by automatically reviewing your code and providing suggestions or pointing out areas of concern. This can speed up the review process and ensure a higher level of code quality.
  10. Exploration and Planning: AI can help generate various implementations for a function based on its signature and purpose, which can be particularly helpful when you’re unsure about the best approach. This can inspire new ideas, guide your next steps, and assist in project planning.

The Challenges in the AI-assisted Coding Landscape

With new technology comes new challenges. Debugging code written by AI-enhanced developer tooling, for instance, is purportedly harder than debugging code written by the engineer. This could potentially offset the benefits of reduced workload and task time.

Another intriguing aspect is how the creative process fits into AI-assisted coding. Is there a risk of “offloading the creative process” to AI?

Studies on AI-assisted prose writing suggest that AI struggles with maintaining a unique style and voice, often reverting to “tropes and repetition”. Could similar issues plague code writing assistants?

The Way Forward

While AI has made significant strides in the software development space, understanding the broader implications of its use remains a work in progress. Future research should focus on the fine line between AI-assisted productivity and creativity, the best ways to harness the benefits of AI in coding without stifling human creativity, and how to tackle the new challenges introduced by these AI tools.

Indeed, the introduction of code writing assistants is transforming software engineering. It’s an exciting era, filled with potential, and it’s clear that these AI tools are only the beginning of a revolution. As we continue to adapt and evolve, we’ll undoubtedly witness a new age in the realm of coding – an age of AI-assisted development that, if navigated correctly, could redefine the software engineering industry.
