In my experience most people won't even learn the ins and outs of the "for those who can't" languages. Worst yet, it's not about the language: most people won't grasp more important concepts that maybe "for those who can" languages force them to know upfront. And clearly while not knowing upfront some things is easier in the short term, it is a recipe for disaster as problems get more complex. So maybe it's about problems "for those who can" and "for those who can't".

People can write bad code in any language. I don't know that "forcing" people to know about it will do anything other than force people to make a possibly bad decision... such as simply marking all values as mutable.

The nice thing about go is that there's just a lot less to know. You can learn everything in a weekend. There just aren't many dark corners in the language.
