Racket remains special at a deeper level, AFAICT. At first glance, it's a wonderful, modern, practical Lisp with many batteries included. Which it is. You can use it as just that. But also, it is a remarkable language for making languages that can interoperate. For example you can freely mix `#lang racket` with `#lang typed/racket` modules, as well as with `#lang my-little-dsl`. The combination of `#lang`s and macros is seriously wicked good.
My own hope is that Clojure will open many more eyes to Lispy ways (including reducing paren-phobia) --- and then many of those people will go on to discover and love Racket, too. Indeed already I see people who seem to appreciate and use both Clojure and Racket. I expect that will increase.
I hope for this too. I really appreciate a "language builder toolkit" part of Racket, although I didn't use it very much yet, I only mixed typed/racket, racket and lazy, which was - as you say - seamless and very impressive. Clojure obviously lacks many features in this area and probably always will be lacking them, because it's not it's focus.
As you say, if Clojure's success helps Racket adoption, then I have no complaints at all. It would be great if people used both Racket and Clojure, one for (almost) seamless interop with C and custom DSLs, the other for interop with Java and concurrency - for example.
I still have hope and believe that Racket will become a successful language. I love Racket and prefer it to Clojure, that's true, but I really hope for Clojure's success too. As I said, they're both Lisps, and having even only one of them "succeed" (in terms of mainstream adoption, they're greatly successful as it is already in their niches) will make me happy. I will be a bit more happy if the one to succeed will be Racket, but I will be overcome with joy when they succeed both. :)
