What’s your take on older languages gaining new life in production because of ecosystem improvements? I’m thinking of Python, which for most of its 34 year history wasn’t always a go-to choice, but nowadays its ecosystem is being scaled with Rust and C++ libraries and tooling. I’ve noticed a similar trend in JavaScript, where Go and Rust are improving bundlers, type-checkers, etc. The way we deploy our software has also changed dramatically with Kubernetes, code running at the edge (thinking of Cloudflare Workers, AWS Lambda).
Python is doing very well, and the really good thing about established languages is that their pros and cons are known. Not many people would choose Python to write a high-performance server or a program that's expected to grow to a million lines or so, and if they do, they have no one but themselves to blame. With newer or less popular languages, you might not know what you're really getting yourself into, and if, five or seven years in, you end up not where you wanted, well, you also have no one but yourself to blame.
