Is this more a matter of preference? Some people feel it is more expressive, others feel it is too verbose. Some people prefer the object oriented design principles, others are turned off by them and really just want structs.

I agree the single file argument is not extremely convincing. Especially because engineers are often on Mac on Windows machine and compiling for Linux. While Go does support this, as soon as you have to use a c library dependency (in my experience this was sqlite), then we had to start compiling in the environment we wanted. Easy to solve with docker but deployment wasn't the reason I like Go.

I should spend some time thinking about why but overall I just "feel" more productive with Go vs Java (including Kotlin). Go's standard library, docs (with links to the source code), everything just feels super readable and understandable.

I don't see much debate agains Go using less memory. I can confirm this was my experience as well. My experience is that it uses a lot less CPU as well.
