Go Cracks Top 10 in TIOBE Feb 2024 – What the Surge Means for Developers
The February 2024 TIOBE index shows Go reaching a record‑high #8, while legacy languages Fortran and COBOL surge into the top‑20, and IBM unveils a generative‑AI tool to translate COBOL code to Java, highlighting the enduring relevance of older languages.
TIOBE Programming Language Index – February 2024
Go reached its highest ever position in the TIOBE index, ranking #8 . The language’s lowest historical rank was #122 in May 2015.
Older Languages Enter Top‑20
Two legacy languages showed significant jumps:
Fortran: moved from #24 (2023) to #11 (2024)
COBOL: moved from #30 (2023) to #19 (2024), just behind Rust
Trend Overview
Both Fortran and COBOL experienced a rapid rise in their index scores around mid‑2023, followed by a modest decline that still left them well above previous years’ positions.
IBM watsonx – COBOL‑to‑Java Translation
In August 2023 IBM released the generative‑AI programming assistant watsonx . The tool uses the watsonx.ai code model to translate legacy COBOL programs into enterprise‑grade Java.
Model characteristics:
Training data: 1.5 trillion tokens covering 115 programming languages
Parameter count: 20 billion
Purpose: efficient, syntactically correct COBOL‑to‑Java conversion
COBOL Usage Landscape
COBOL, originating around 1959, remains critical for large enterprises handling billing, payroll, and transaction processing. A 2022 survey reported:
92 % of respondents consider COBOL strategically important
Estimated active code base: 77.5 billion – 85 billion lines (approximately three times earlier estimates)
