I don't think it's a good long term strategy for Go even if it can be a good one for how Google uses Go now. There are a lot of tools written in Go, docker/kubernetes are maybe the poster children but for something like InfluxDB (disclaimer, they give me a t-shirt :) ) it's worrying. > Mind you, I'm not a fan nor a user of Go so I'm referring purely to their > stipulated strategy on how to evolve their GC.
