I've used many languages in my career, including Java, Scala, Ruby, and Node. I didn't really consider Java, for a couple of reasons.
- I didn't love the Java tooling at the time. Maven for example. - I don't love OOP. Go has just enough OOP patterns for me.
I tried Go as an experiment, but didn't know it would become my go-to language. What I found was super fast build times (big win), built in testing, and a simple language that almost anyone can understand (versus the relative sophistication of something like Scala).
