Top Programming Languages 2025: IEEE’s Annual Rankings and the AI Impact
IEEE Spectrum’s 2025 programming language rankings reveal Python maintaining its dominance while sparking debate about whether AI assistance makes language choice increasingly irrelevant.
Python Leads, Java Follows
Python secured the top position across IEEE’s rankings, with Java claiming second place. The results combine data from search engines, Stack Overflow activity, GitHub repositories, and job postings to create composite scores for language popularity.
TypeScript and JavaScript split the traditional web development vote, appearing as separate entries rather than combined metrics. When viewed together, they would challenge Java’s second-place position.
The AI Abstraction Argument
IEEE’s analysis suggests AI assistance reduces the importance of language-specific knowledge. The report argues that just as developers rarely consider CPU instruction sets today, AI tools may eventually make programming language choice a “minor detail.”
This perspective faces significant pushback from the developer community. Critics point out fundamental differences between hardware abstraction and language selection:
Hardware abstraction works because:
- Compilers generate deterministic output
- Bug reports go to maintainable vendors
- Edge cases are rare and well-documented
AI code generation differs because:
- Output varies between identical prompts
- Debugging falls entirely on developers
- No vendor support for incorrect AI suggestions
Methodology Questions
IEEE’s ranking methodology draws from multiple sources, but each has limitations:
- Google search results include non-programming content and vary dramatically over time
- Stack Overflow data reflects beginner questions more than actual usage
- Academic papers skew toward research languages like Python
- Job postings may include fake listings or outdated requirements
These data sources can create misleading impressions. COBOL ranks higher than many modern languages despite minimal new development, while emerging languages like Zig don’t appear at all.
The Enterprise Reality
Java’s strong showing reflects its continued dominance in enterprise development. Financial services, healthcare, and large-scale systems still rely heavily on Java ecosystems. The language benefits from:
- Extensive tooling and IDE support
- Massive library ecosystem
- Large pool of experienced developers
- Proven scalability in production systems
Meanwhile, Python’s top ranking stems from its role in data science, AI research, and educational programming. The language serves as both a beginner-friendly option and the foundation for machine learning frameworks.
Language Consolidation Concerns
The discussion raises questions about AI’s potential to ossify current language preferences. If AI tools perform better with popular languages due to training data volume, new languages may face higher adoption barriers.
This could create a feedback loop where:
- Popular languages get better AI support
- Better AI support increases adoption
- Increased adoption generates more training data
- More training data improves AI support
Looking Forward
While AI assistance continues improving developer productivity, the fundamental differences between programming languages persist. Performance requirements, ecosystem maturity, and team expertise remain crucial factors in language selection.
The debate highlights a broader question: As AI tools become more sophisticated, will they democratize programming across languages or concentrate development around a few AI-optimized options?
For now, the rankings reflect current usage patterns rather than future trends. Python’s dominance in AI and data science, Java’s enterprise stronghold, and JavaScript’s web monopoly continue driving their popularity regardless of AI assistance quality.
