Your people can pick up go reflect package or go routines/channels and co in 1-2 weeks and start contributing? impressive... most people can pick up for loops, if,switch statements, variable and function declaration in a week in any language as well...
In fact, a lot of non programmers use JS regularly to write scripts in the browser. I imagine your people know how to program before hand... So what do you think takes longer to learn? mastering go threading model or being able to add interactivity to the DOM?
