Thanks for reading my post and taking time to write about it.

As the title of post which emphasizes on "WHY GC matters", I tried to reason why we should understand the underlying of a system, say Erlang, Go, Java or whatever else. But unfortunately always there are few documentation around about them and sometimes it is advised not to read them.

I do agree with you that comparing languages with very different goals is totally wrong, but what I did was comparing the Go's documentation author advice with mine, which is about being clever enough to understand your system.
