In Germany or maybe Europe(?) many enterprises use Java for completely new services.

Some reasons I found: - it's a matured stack with a matured framework (Spring)

- there's already a lot of Java knowledge in the company

- there are already existing services written in Java. Why should the company start to maintain another stack?

- there's a lot of Java knowledge walking outside the company. So hiring is easier.

- it's still taught as one of the first languages at universities.

I've only seen few alternatives for language usage:

- C#, but then you lock-in to Microsoft.

- Typescript, but there are still skeptics

Anyway, the number of companies who are adapting other languages like Go or Python is rising. That's my biased perspective as a Cloud developer working in finance, IIoT. I don't know how it looks like for other areas.
