It seems weird to switch from python to go. Python is lispy in that it maximises flexibility and developer power at the cost of speed and inbuilt correctness checks. Go is Javaish in that it limits what the developer can do heavily (crippled typesystem) for speed, correctness.

I checked my assumptions, you're kind of right about python developers switching but it's hard to know the real base distribution of people who know those languages (there might just be more python/js developers not more switching proportionally). Not much ruby guys though and plenty of Java/C/C++
