Back in 2010, the trendy language was Ruby. Many companies were built on Ruby. Yet, PHP programmers were the silent majority. More recently, Rust, Elixir, Zig, Kotlin, TypeScript and others have been getting a lot of attention. Yet, in my industry - web development - PHP may still be king of the hill on the server, and JavaScript on the client.

My guess as to why this is - they became big first and were "good enough" - and no one's rocking the boat by introducing big changes on a regular basis.

My research shows that in aviation, Ada is still huge. In banking, Cobol. In automotive, C/C++. In embedded, it's C/C++. In data science, Python. In enterprise systems, Java. But, I don't know the "why", although I can guess.

Yet, if you were to browse Hacker News, you'd be lead to believe that the new kids on the block are absolutely crushing it.

I think Rust might be the go-to language for Crypto companies, but I don't know for sure.

It's difficult to separate signal from noise. So, that begs the question: in your industry, what languages and tools are dominant? Why? What's the penetration of newer languages like - is anyone losing sleep that their bread and butter is going to go out of style? How about No-Code tools? have they taken over?

Thank you!
