The more languages you have the more you have to know just to know what the software knows. This makes things hard. Heck jumping from what I call back end languages like Go to Java to C# requires a mental switch if you've been doing one for a week or more. I'm using Go now, but I've got 13 years of Java experience with a Java Ring (https://images.techhive.com/images/idge/imported/article/jvw...) on my hand. When I switch back to Java I mutter the phrase, "Nope. Nope. Nope. That's Go, not Java."

You should use the right tool for the job. Python is good for AI stuff. Java is good for performance and maintainability. Go is interesting any might give Java a run for its money.

You should limit adding tools because they're cool. Do that for bow ties not code.
