Which makes Go a great option.... if you use it properly. It means you don't need to worry about a programmers language history when you hire even if you need them to be productive right away.
It means you can hire the smartest developers, regardless of whether they have been doing embedded work, or spas in js, or large enterprise application dev in java, etc.
If you are a good Haskell/D/Lisp developer then switching to Go will probably halve your productivity over the long term.
There are a lot of benefits to using Go but lets not pretend there aren't any downsides.
