2023 Go/Rust Is Slowly Encroaching on Java/Python Territory
O’Reilly recently released the 2023 annual technology trend report, and research shows that developers’ interest in key components of generative AI is accelerating: content about natural language processing (NLP) increased by 42% year-on-year, followed by deep learning (23% ).
Developers are also increasingly searching for content related to transformers, the AI models that have led to huge advances in natural language processing. O’Reilly believes the move reflects the impact of Open AI’s GPT-3 and ChatGPT developments on the market, as well as public expectations for upcoming products from Google, Meta, and others. Developer interest, on the other hand, fell 14 percent in reinforcement learning and 5.8 percent in content about chatbots.
In terms of programming languages, Java and Python are still far ahead and have a small increase of 1.7% and 3.4%, respectively, there is a large increase in interest in Go (up 20%) and Rust (up 22%). If this growth continues, it could soon directly challenge Java and Python, the report said. Go is the third most popular language among them, followed by C++, JavaScript, C#, C, Rust, TypeScript, R, Kotlin, and Scala.

Containers, Linux, and Kubernetes are hot topics. Containers grew 2.5 percent, with Linux and Kubernetes each growing 4.4 percent over the past year. Content about Service Mesh dropped 28%, while content about Istio dropped 42%.
The study also found that among data topics, content about Microsoft Power BI was the most used, with a 31% year-over-year increase, “Power BI has established itself as the leading business analytics platform”. Apache Spark remains the most widely used data tool, while data platform Hadoop has taken a back seat.
Some other findings include
- In terms of cloud services, AWS remains the most popular, followed by Microsoft Azure and Google Cloud. While the Big Three dominated, their usage was down year-over-year: AWS was down 3.8%, Azure was down 7.5%, and Google Cloud was down 2.1%. The most popular cloud topics include cloud migration (up 45 percent), cloud service models (up 41 percent), and hybrid cloud (up 28 percent).
- Interest in coding practices grew by 35%, the largest increase among software development topics, indicating that developers are highly motivated to improve their programming skills. Within the same thematic group, quantum computing grew 24% year-over-year.
- Two of the biggest security themes over the past year include zero trust (up 146 percent) and secure coding (up 40 percent).
- Developers are often looking to improve their “soft skills,” with visits around topics such as project management (47 percent increase), professional development (37 percent increase), and communication (26 percent increase).
- The biggest drops in search frequency were for cryptocurrencies, Bitcoin, Ethereum, and Java 11.
