I think you're looking at this the wrong way. There's a place for programming languages like Go. A tool does not have to "full featured" or "hard" to be good. And using "simple" tools does not make someone more dumb.
If you need a swiss army knife, then by all means use one. If you need a drill, Go ;-) with that.

There is beauty in simplicity as well.
