Benchmarking is error prone, and so are language statistics. Certainly Go has had a meteoric rise and much of the big innovations are happening in Go (Kubernetes, Docker, Prometheus, Terraform).
Go is simple, easy to install, and the benifits of a compiled language are huge. I can apply all of my systems knowledge to understand how my app is performing. The JVM is a career in of itself, and locks you into an ecosystem that is very proprietary and frankly full of lame enterprise salesmen and big business fogies. Go is fun. It’s branding is fun, it’s community is passionate, and a lot of big names are on the tin that speaks to a lot of us who love and grew up on Unix.
I mean, do you want to support Oracle and Larry’s bid to buy more islands or ken and rob?
