Nothing. But Schemers just passionately hate it since the 70s because it doesnt enforce their religious dogmas like recursion, continuations, unusable macros, and other similarly silly pretexts.

The fact that the GNU extension language became a Scheme instead of a Lisp is primarily a very personal decision by Richard Stallman. Early Lisp Machine companies like Symbolics refused to copyleft their stuff, so RMS started to hate them with a passion.

So even as he was a Lisp fan early on, which can be seen in Emacs, he for political reasons switched the GNU projet to Scheme, even as the GNU project had no working Scheme implementations but had two Lisp implementations (CLisp and GCL).

So to answer your question: Nothing is wrong with Lisp, but the dear leader hates it, because the Symbolics guys were meanies when he was 25 yrs old.

You might want to read a less harried account on the history of Scheme than this.

Wikipedia names continuations, tail recursion in the standard, hygienic macros and a shared namespace for variables and procedures as defining differences between Common Lisp and Scheme.

Wow, your comment history is really full of classic troll stuff. "HN is throughly infected with the communist delusion, commonly observed with atheist intelectuals." Check yourself, dude.
