Being aware of overengineering is crucial when working with a feature-rich language like C++. Overengineering occurs when developers introduce overly complex or unnecessary solutions to a problem.

C++ developers could be attempted to use as possible the new features introduced by the new standards. which makes the code finally more complicated than it must be.

Here’s an example to show how C++ metaprogramming can be used to create a type-erased container with arithmetic operations that are evaluated at compile time. While this example show the power and flexibility of C++ metaprogramming techniques. it might seem complicated due to the use of templates, concepts and constexpr functions:

C++ has a steep learning curve compared to some other programming languages. Its syntax and concepts can be complex, especially for beginners or those transitioning from higher-level languages. C++ may not be as beginner-friendly as some other languages, it offers unparalleled power, flexibility, and opportunities for those willing to invest in learning and mastering its intricacies. 

The level of experience, particularly with active development spanning more than five years, often correlates with a deeper understanding of C++ and its capabilities. Developers who have been actively working with C++ for an extended period tend to have a comprehensive knowledge of the language’s features, nuances, and ecosystem, enabling them to leverage its power effectively in various applications.
