Go gives you the illusion of simplicity because it gets rid of guard rails and error checking. If you remove all error checking, of course your code is going to look a lot simpler. It's also going to be a lot more wrong and crashy.
Wait until your code base grows, your team grows to >10 developers, and you will understand what I mean.
Java (and preferably Kotlin) are a lot more serious about making sure your code is robust before it compiles.
