The root of the eventloop issue is not Node-specific. The real underlying issue here is that one CPU core is given too much work while others are more or less idle. Offloading some of the work to another process naturally solves this issue - It doesn't really matter that this other process is a Go program or a Node.js one - Both approaches would have solved the problem. Attributing credit to Go itself for solving the issue is disingenuous.
If you ran Go as a single thread, you would also run into similar issues. The main advantage of Go is that it makes it easier to parallelize your code thanks to goroutines and channels (a single source file can encapsulate the logic of multiple concurrent processes).
That said, I find that this 'ease of concurrency' makes Go code less readable. In Node.js, it's really easy to identify process boundaries since the child_process module forces you to put code into different files and communicate via loosely coupled IPC channels.
Most of the Node.js vs Go arguments are weak. It's surprising that Node.js is still outpacing Go in popularity in spite of all this slander.
