Writing bug-free shared memory concurrency programs with Go is trivial. Your opinion is based on outdated information.

You are reading something I did not write. I am not obsessed with the nonblocking mantra. Blocking is not inherently bad. Multi-processus is also a perfectly valid concurrency model.

Nor am I obsessing about being ultra performant to achieve the revered C10K when I don't need to or can get around it. That was my point.

Not everybody is Facebook or Netflix. For the vast majority of small and medium enterprises, it faster, simpler, safer (and possibly cheaper) to quickly develop a blocking program without thread and spawn multiple processes.
