JS apps nowadays have so many layers that often something breaks over time or if you run it with the wrong version of node.

Frontend post react is an absolute nightmare: My experience with a fleet of semi abandoned next.js static websites is pretty terrible: just in months something stops working in my pipeline on vercel and I need to spend time to debug it. Running things locally is even worse, I just change the code, push and hope for the best.

Python is a downright nightmare: between 2vs3 and pip, egg, venv, I usually just salvage the code I need and try to make it work or convert it to something saner (eg. I did that with an opencv algorithm I found - I just transposed it to rust + the same opencv api calls). My favourite story happened literally 2 days ago. I was trying to install a dependency (keras_ocr) and I kept failing on some dependency; I tried installing that dependency manually and it worked but no success on installing keras_ocr. Eventually I updated pip and it started working.

I had huge problems running old Go software, I think I succeeded once after a lot of pain and gave up the other times.

I had fairly good results with ancient C, C++, Java and Haskell. Probably because they started before we had cool and glamorous developers on twitter selling you a course and not maintaining his 200 leftpad libraries.

I'm curious to see where Rust will sit in a few years.
