Why would you choose Golang for your company?

> I guess ultimately the big question is that if I am just building a web service that does not need to serve millions of users at the same time, will I choose Golang?

Depends on the number of users per machine (or cloud capacity per $) I need to budget for. I can write Python easier and faster, but sometimes I need more performance per server, and I can write more performant and efficient processes in Go. Its not that one OR the other is better, but a case of Right tool for each task.

Of course Rust or C would take that further, but the effort also increases only due to a lack of familiarity with those in my example case.
