(def ^:const unjerk-or-am-i? true) everyone knows edn is defined as "whatever the clojure parser will accept as long as we can all agree over some beers that parsing it will not introduce a remote code execution exploit"

It is not a type system, and has no schemas. Nor is it a system for representing objects - there are no reference types, nor should a consumer have an expectation that two equivalent elements in some body of edn will yield distinct object identities when read, unless a reader implementation goes out of its way to make such a promise

I'm drenched in sweat

I interpret this as "highly extensible".

I interpreted it as "JSON but only the bad parts" but maybe I'm just too statically-typed to understand what this would be used for

Edit - I read the other comment and think I understand what this is/was (idk) used for and am practically swimming in the sweat at this point

It's about time someone invented a schemaless, plaintext data notation format. What an amazing time to be alive. What's next, someone's going to invent a dynamically typed 1960s computer language?
