It's pointless to complain about the size of "hello world". It's not a real program. In Go's case it's larger than a C binary because the libraries (and the presence of a runtime) are capable of much more under the covers, but by the time you write a real program in Go you'll find the ratio of Go binary to C binary isn't nearly so large; the incremental cost to the binary of a Go source file compared to a C Go file is negligible.
