C# or Python
Short summary
C# excels for enterprise systems requiring long-term maintenance, type safety, and CPU-intensive work; the .NET runtime is fast and tooling is excellent. Python dominates AI/ML, rapid prototyping, and data science; the ecosystem is unmatched and iteration speed is crucial. Performance myths matter less than ecosystem fit—NumPy/PyTorch operations run in C/CUDA, not Python. Choose based on team expertise, required libraries, and problem domain, not language syntax.
- •C# best for enterprise systems, type safety, CPU-bound work, and long-term maintenance
- •Python best for AI/ML, rapid prototyping, data science, and when data scientists contribute
- •Choose based on team expertise and required ecosystem, not abstract language quality
