It's amazing to see more and more finding Go. For a lot of us it's been almost a decade since we started using it. Back then for me it was the perfect blend between C and ruby. Today I believe it's the language of distributed systems and the cloud. I personally think Go ends up with majority marketshare for all cloud native systems and its already going in that direction with the core tools like docker, kubernetes, etcd, grpc all using it. By extension of that I believe a signifcant number of backend systems and services in the cloud will also predominantly be Go based.
This doesn't rule out other languages, its merely an indicator of a trend we've seen time and time again related to platforms. Windows, Linux, Android, etc. Every platform has a dominant language. Other newer up and comers like typescript, rust, swift, kotlin, etc have their place but for their respective platforms.
Go's adoption will accelerate in the next decade but you'll also find it disappear into the background as development as a whole levels up beyond the languages of today.
Only us millenials and older generations will speak of it. The next generation will be preoccupied with an entirely different model of programming.
