The flip side of that coin is you're liable to get someone reinventing the wheel - poorly - in whatever language doesn't have all those goodies.

Yep, Greenspun's tenth rule comes to mind.

In the Erlang world, we call that Virding's rule:

"Any sufficiently complicated concurrent program in another language contains an ad hoc informally-specified bug-ridden slow implementation of half of Erlang."

Edit: I'll add, though, that the Go people are pretty smart and seem like they're doing good things, so I wouldn't be too complacent in thinking Erlang is the only game in town. It still does get some things right that are hard to replicate in Go, though.
