While the use of Rust language by professional programmers continues to grow, Rust users expressed concerns about the language becoming too complex and the low level of Rust usage in the tech industry, according to the 2023 State of Rust Survey report.

The report, which was produced by the Rust Survey Team and published February 19, noted a slight jump in the number of respondents that self-identify as a Rust user, up from 91% of respondents in the 2022 survey to 93% in 2023. The survey was conducted from December 18, 2023, to January 15, 2024, and drew 11,950 participants, 9,710 of whom (82%) completed the survey.

Among the 9,374 respondents who shared their main worries for the future of Rust, 43% were most concerned about Rust becoming too complex, a five percentage point increase from 2022; 42% were most concerned about low usage of Rust in the tech industry; and 32% were most concerned about Rust developers and maintainers not being properly supported, a six percentage point increase from 2022. Further, the percentage of respondents who were not at all concerned about the future of Rust fell, from 30% in 2022 to 18% in 2023.
