Why I Switched from Python to Go (After 5 Years)

Hey,

After 5 years of working professionally with Python, I made a big switch — to Go.

Everyone knows Python is winning in every metric: salaries, jobs, popularity.

But more and more senior engineers — like me — are quietly switching to Go.
Here’s why (short version):

🚀 Performance

• Python is slow (interpreted + GIL bottleneck).

• Go is compiled, statically typed, and built for true concurrency — you can actually use all your CPU cores.

• Massive companies are rewriting critical systems in Go and reporting huge performance gains.

🧠 Simplicity (for Professionals)

• Python feels simple when you're learning.

• But in large systems, Python’s dynamic magic turns into a maintenance nightmare.

• Go forces explicit, predictable, boring code — and that’s exactly what scales.

🔒 Real Typing

• Python's type hints are just fiction — it's still runtime-checked.

• Go enforces types at compile time — catching bugs before they happen.

• Plus: you get low-level control (like pointers) without the dangers of C.

🛠 Code Quality

• Python lets you (and your teammates) write awful code.

• Go forces clear, correct patterns — and won’t even compile if you don’t handle errors properly.

• At scale, strictness is not a pain — it’s protection.

I break all of this down (with real examples) in my new YouTube video:

If you’re a Python engineer curious about Go, or just thinking long-term about your craft — I really think you’ll enjoy it.
