Exactly. It's hard to even really comprehend how deep his influence goes; we're so surrounded by it's hard to even see it sometimes.
Consider that every single person reading these words are doing so using technology he created -- after all, even if you're not on a UNIX derivative you're probably on an OS and web browser written in C.
How much code is written every day in C and its descendants? How much more in languages that themselves are written in C?
dmr is part of an very small group of computer scientists that truly changed the paradigm of computing for everyone everywhere (Turing, von Neumann, Engelbart, ...) As long as there are ones and zeros his name will be remembered.
What would the world look like if C would have been never invented? I guess our browsers would simply be coded in Turbo Pascal dialect.
And Visual Basic is still huge (#12 on langpop.com). Also someone could reasonably argue that from the concept and ideas SmallTalk and Lisp were way more influential than C.
That said, I feel a bit dirty to make this argument. Dennis Ritchie should be praised for his accomplishments.
Regarding your last point, while the ideas of Smalltalk and especially Lisp are influential, C may have just as much a claim to influence. Both Lisp and C are beautiful abstractions, the assembly languages of two abstract machines. While Lisp is powerful, C is such a profound success because the C abstract machine is very close to how computers actually work.
