Should I learn Scala or Go?
Use GO if you run in the cloud, specially Google Cloud. Use Scala if you depend on the JVM or your development team are already familiar with Java. Use Scala for high concurrent distributed systems that take advantage of the JVM optimizations. Use Scala for Big Data, specially Spark.
