Artificial intelligence (AI) is one of the most exciting and impactful fields of the 21st century. AI applications range from self-driving cars, to natural language processing, to computer vision, to healthcare, and more. However, developing and deploying AI systems is not an easy task. It requires a lot of computational power, data, and expertise. Moreover, it poses many challenges and risks, such as security, reliability, scalability, and ethics.

One of the key factors that influences the success of AI systems is the choice of programming language. Programming languages are the tools that enable developers and researchers to express their ideas, implement their algorithms, and interact with their data and models. Therefore, the choice of programming language can have a significant impact on the quality, efficiency, and usability of AI systems.

Traditionally, low-level languages, such as C or C++, have been the dominant choice for AI programming, especially for building the core components of AI frameworks, such as TensorFlow, PyTorch, or MXNet. These languages offer high performance, fine-grained control, and compatibility with existing hardware and software. However, they also come with many drawbacks, such as complexity, verbosity, and error-proneness. These drawbacks can make AI programming more difficult, time-consuming, and risky, especially when dealing with large-scale and complex AI systems.

On the other hand, high-level languages, such as Python, have been the preferred choice for AI prototyping, experimentation, and analysis. These languages offer simplicity, readability, and productivity. They also have a rich and diverse ecosystem of libraries, tools, and resources for AI, such as NumPy, SciPy, scikit-learn, pandas, matplotlib, and more. However, they also have some limitations, such as performance, concurrency, and interoperability. These limitations can make AI programming less efficient, scalable, and robust, especially when deploying AI systems in production environments.

Therefore, there is a need for a programming language that can bridge the gap between low-level and high-level languages, and offer the best of both worlds for AI programming. A programming language that can provide fast, efficient, and memory-safe systems programming, as well as simple, readable, and productive AI programming. A programming language that can support concurrent and parallel execution of multiple AI tasks, as well as integrate with existing AI frameworks and tools. A programming language that can enable the development and deployment of secure, reliable, and scalable AI systems.

One such programming language is Rust. Rust is a low-level programming language that aims to provide fast, efficient, and memory-safe systems programming. Rust was created by Mozilla in 2010, and has since gained popularity and recognition among developers and researchers. Rust has been ranked as the most loved programming language by Stack Overflow users for six consecutive years, from 2016 to 2021. Rust has also been used by many companies and organizations, such as Microsoft, Google, Amazon, Facebook, Dropbox, Twitter, and more, for various projects and applications.

Rust has some advantages for AI programming, such as:

• Memory safety: Rust’s borrow checker ensures that memory is managed correctly and prevents common errors like buffer overflows, dangling pointers, or memory leaks. These errors can compromise the security and performance of AI applications, especially when dealing with large datasets or complex algorithms.
• Concurrency: Rust supports real multithreading and allows concurrent execution of multiple tasks without data races or undefined behavior. This can enable parallel and distributed training of deep learning models, which can speed up the learning process and handle larger models.
• Performance: Rust is designed to be as fast as C or C++, but with more guarantees and less overhead. Rust can also leverage existing C or C++ libraries through its Foreign Function Interface (FFI), which can be useful for integrating with existing AI frameworks or tools.
• Ecosystem: Rust has a growing and active community of developers and researchers who are interested in AI. There are several libraries and projects that aim to provide AI functionality in Rust, such as [tch-rs] (a wrapper for PyTorch), [tract] (a neural network inference framework), or [rusty-machine] (a machine learning library). Rust also has a [jupyter kernel] that can enable interactive development and prototyping of AI ideas.

However, Rust also has some drawbacks for AI programming, such as:

• Learning curve: Rust is a fairly complex language and requires a solid knowledge of software engineering principles and systems programming. Many AI practitioners and researchers may find it harder to use and it may slow them down, especially if they come from other fields or are used to scripting languages like Python.
• Maturity: Rust is a relatively young language and its AI ecosystem is still developing. Compared to Python, Rust has fewer libraries, tools, and resources for AI, and some of them may not be stable or well-documented. Rust may also lack some features or abstractions that are useful for AI, such as automatic differentiation or dynamic graphs.

In summary, Rust is a promising language for AI programming, as it offers memory safety, concurrency, performance, and a growing ecosystem. However, Rust is also a challenging language to learn and use, and its AI ecosystem is still maturing. Rust may be more suitable for low-level or performance-critical AI tasks, such as building kernels, engines, or frameworks, rather than for high-level or exploratory AI tasks, such as prototyping, experimenting, or analyzing data.
