If you can think in terms of pipes, Go makes you productive.  I recognized that about 13 hours into learning Go about two years ago.

Reductions in latencies from 300ms to 500us in 4 years. Good story
here about how latency is cumulative:

https://blog.golang.org/ismmkeynote

The very first thing I learned about go, was how to turn off the
garbage collector. I guess I have to go learn some go, for real, now.
