I used this playing with a Lapis project years ago. It very much fit the zeitgeist in the wake CoffeeScript's popularity. Although usable, it feels a bit dated now and a product of its time. The zeitgeist now requires static typing.
Fashion only cycles on equivalent choices. Some stuff are better or worse than the alternatives, so they stick either in use or out of it.
Types are one of those things that will stick in use. We will also probably see a wild diversity of type systems in experimental languages, as there is very likely one better than everything we use today.

Even if that is true, there are potentially a lot of dimensions to consider in solving the problem of what is better or worse. Some of these dimensions, or where in that dimension what-is-better falls, take a long time to discover and are different for different problem spaces. Sometimes you think you've got it right only to learn that you were wrong much later.
But it isn't true. Fashion is by any indication only loosely concerned with utility and sometimes settles on downright masochistic flavors-of-the-day.
