“Hogging” memory correlates with better throughput in case of GCd languages, and Java really shines on this front, it is not an accident that it is the numero uno choice for big backend services. Performance is also not really in favor of Go besides basic examples where value types can help. Any bigger example, and heap allocation won’t be avoidable and Java’s GCs are the state of the art to a huge degree.

And the final point, why reinvent the wheel each time? Go recreates a bunch of tooling, ecosystem that already existed.
