When comments are not included in code, it can lead to significant challenges in understanding and maintaining that code in the future. Comments serve as a vital form of documentation, providing context and explanations for various parts of the code. They help explain the purpose of functions, the reasoning behind specific implementations, and any important details that aren't immediately obvious from the code itself.

Without comments, someone reading the code later—whether it’s the original author after some time or another developer—may find it difficult to discern the logic and intent behind certain decisions. This can result in increased time spent trying to understand the code, making updates or fixes more complicated, and potentially introducing errors as modifications are made without a clear understanding of the original design.

While it is true that code will still run without comments, the clarity, maintainability, and collaboration aspects greatly suffer, especially in more extensive or collaborative projects. Thus, including comments is essential for effective coding practices, ensuring that code remains accessible and understandable to others (or even to yourself at a later date).
