Kotlin vs Golang

Hi folks. I am a software engineers in one of the biggest companies in my country. Within our code base, there is almost a 50/50 split between microservices written in Go vs the ones written in Kotlin.

I am very interested in hearing your opinions about the advantages/disadvantages about each language, and most of all:

If you had to convert your entire code base and keep only one of them, what would be your choice?

Ill kick this off by giving my perspective:

I am inclined to lean towards Golang as long as we are taking about microservices exclusively as I think that thats where it shines. Whenever you start adding too much abstractions, ( and your service starys away from actually being a microservice ) then Kotlin can help a lot.

But as long as you stay put within that realm, then Go is the clear winner. Ill point out some of the biggest advantages:

1. Native 100% and multiplatform
2. Performs way better
3. Its simpler to read and more opinionated.
4. Way easier to learn, this is even more true when talking about Junior team members.
5. Its dependency management is a breeze.
6. It compiles waaay faster ( specially useful when writing unit tests ).
7. Totally the opposite of bloated, unlike Kotlin.
8. You stay away from anything JVM related and thats always a plus ( haha just kidding…)

While for Kotlin:

1. It allows you to create very powerful abstractions ( sometimes too much and you feel you are using a Nuke to kill a spider)
2. Its constructs and syntax are way more refined.
3. Generics… yaaaay!! ( yes. I know Go has generics now )
