Affordable lowercase letters for a few decades now. Most of us just call it Lisp.

That's one thing I am acutely aware of and monitoring closely, and in fact it's one of the blog posts that's ripening to be released sometime: Am I building a Lisp?.

And every once in a while it looks like it might be that I am, in fact, arriving at a Lisp, but in the end they turn out to be false alarms, so the answer is still fairly resoundingly: No.

The only thing lisp seems to have not figured out yet is this small thing we call "Syntax", which the PL community mostly figured out 50 years ago : you write terse notations and the compiler builds up the tree for you, you don't layout the syntax tree yourself.

Lisp also seems to have a shortage of knowledgeable advocates who understands other programming languages enough to know that not everything is or needs to be a lisp.
