I don't even like Node, but it is hard to imagine that Swift will get adoption faster than Node.
If 100% of Objective C users switch the adoption could be fast since you'd have a new mature-ish language as the preferred language for a large install base. But I don't see the libraries and modules being there to allow most devs to just switch right away.
Obj-C libraries have interfaces auto-translated to Swift, so barring some edge cases are already entirely usable.
Writing a Swift app isn't a problem right now because of lack of library support, but mostly because the compiler still likes to segfault and taunt you. Frequently.
Either way, I like the language, I've been working with it for the past month, and it's neat and brings a bunch of really nice concepts to the table.
But "remake computer programming"? Wut.
Swift will quickly become the standard for OSX and iOS code, but that is but a tiny corner of programming-dom.
I shared because I think it is worth hearing the claims even if I don't share the author's view.
It's only a thing for apple developers.
