Lets assume that as an individual I want to move away from Java for backend development and currently I use Spring. Is there another ecosystem with a great IDE, type safety (or just type annotations), limits that allow one to not shoot yourself in the foot, a good debugger, memory safety and lastly speed ? Python really shines in most of the above except for the speed part.

Why not just use openJDK? Seems a bit drastic to do a full rewrite.

I agree. I wouldn't consider a full re-write but for further development.

Sounds like you might be looking for C#, but I'm sure you've considered it already.

But why would you want to move away from an ecosystem with a great IDE, type safety, speed and limits that prevent yourself from shooting yourself in your foot?

You could look into dart. Take a look at http://aqueduct.io/ for an example.

I have to plug Angel, too: https://angel-dart.github.io/

The Python speed issue in my experience is almost never a material concern. It’s fast enough using the CPython reference implementation, and there are numerous options (PyPy, Cython) to squeeze out better performance if you really need it.

Go is pretty decent from a few releases back.

If you're using JetBrains IDEA Ultimate, the official JetBrains plugin for Go works really well. It's the same piece their GoLand IDE uses.

Node.js, optionally with TypeScript, and VS Code as an IDE

Numba provides a Python decorator (like Java annotations) to opt in to native compilation: http://numba.pydata.org
