I have had a great time learning Go and working with containers, so that stack is intriguing to me - I think I would be "all-in" Linux and Go. Ironically, Linux was one of the first platforms I wrote code on because it had such a superior networking experience on the Internet in the early 90s, but because the businesses I worked for were Microsoft environments that's where I built most of my experience and knowledge. I love what I do on the .NET Platform but if I were to have a second option it'd be a Linux/Go/Docker path for me.
