Go vs Python for Backend Services: A Pragmatist's View

I've run both in production at scale. The answer isn't one-size-fits-all, but after writing hundreds of thousands of lines in each, I have opinions. Strong ones.

Go vs Python for Backend Services

This is a placeholder. Replace with your actual content.

Where Go Wins

- Latency-sensitive services - High-concurrency workloads - Services that need a small binary/container - Teams that want to avoid runtime surprises

Where Python Wins

- ML/data processing pipelines - Rapid prototyping - Teams with strong Python expertise - Scripts, CLI tools, one-offs

My Default

Go for new services. Python when the ecosystem matters (ML especially). Never rewrite for ideology alone.
