Mesos core is legacy (pre 11) C++ code nobody wants to maintain.
This is actually very very VERY important. Go is a lot more concise (IMO) that C++, generally when I'm curious about how something works in a project written in Go, its much easier to follow the logic.
Go is nice. I like it a lot. It's very readable, it reduces the number of good ways you can do something to usually just one, it's fast, fat binaries are awesome, great concurrency primitives, etc...
There's something to be said about how the code is written. I've seen easy to read C++ and hard to read go (I found go's built in http server source code to be a tough read) and vice versa. In Mesos we strive to write very readable code and so I would hope that despite being modern C++, it is approachable for an uninitiated reader.
