In the 9 December 2022 issue, the Research Article “Competition-level code generation with AlphaCode” (Y. Li et al., p. 1092) and the accompanying Perspective, “AlphaCode and ‘datadriven’ programming” (J. Z. Kolter, p. 1056) describe an artificial intelligence (AI)–based system for generating code. The authors explain that the system can be used for small coding problems, such as tests for computing students, and that they are far from being useful in computing applications that include millions of lines of code, such as word processing. As we enter an era of AI where tools like AlphaCode and chatGPT will change how tasks are performed, it is important to understand the boundaries of what they can and cannot do.
