for large systems, you really can't beat the implicit infra that Java and .NET bring to the table. I am dealing with 20 year old VB code that interops with new .NET core code just fine. Try saying the same for Python.
The larger issue with Go, which Go enthusiasts will downvote me for, is that it allows for writing absolutely garbage code that is impossible to read. Readibility is king in software development, and developers spend 80% time reading it. I won't go into the details here, but Go has no constraints for how code should be structured, leading to spaghetti code. I have first hand experience, and 30 years professional experience.
Go isn't a serious language for large systems. The language allows writing shitty code and the community has largely adopted that. Go fanatics will hate this, but you simply can't compare it with the ability to write and maintain in languages like Java.
