There are plenty of complicated things in Go, IMHO where it shines best is judiciously providing incredibly nice interfaces atop the complicated things.
Having coded in go professionally, I disagree. Go abstractions leak in weird and unexpected ways that are surprisingly different to it's C/C++/Java predecessors.
Goroutines were kind of the raison detre' for using go. But using them wasn't simple, and instead often goroutines brought their own issues. See here:
Often a programming language takes a first guess at the problems they want to solve, and often get them wrong. C++ is probably the most notable language in this category here.
That said, I do appreciate an attempt to improve programming languages even if it undermines the primary feature of the language itself.
