These Are the Most Important Programming Languages in 2025
Trending: Python and Java remain firmly in first and second place, but C++, C, and even the less popular C# in recent years have re-established themselves at the top in 2025. Go has dropped significantly in the trend barometer and now ranks 11th (in 2024 it was 7th). Rust also seems to have suffered losses (from 10th to 15th place), but appearances are somewhat deceiving: while in 2024 there was a relative share of 0.1544 Rust queries for every Python query, this slightly increased to 0.1763 in 2025. Generally, there is a relative increase in searches for other programming languages—which is also an indicator of the growing use of AI assistants. (Image: IEEE Spectrum) 3/6 Back to the Article
