Lisps are not write-only. They're easy to read precisely because there is no inscrutable syntax. Every pair of parentheses has a first element, which tells you what they're doing. The parentheses denote a scope in which to look for arguments.
Conventional style guides also make the readability practically a trivial issue because you end up indenting arguments such that the structure of the program is reflected in the indentation, because each S-expression within a parenthesized S-expression is itself an AST node. Writing readable Lisp is just a matter of reflecting the AST's structure in the indentation, which most people do in other languages anyway (to some degree).
> the advantages of lisp have long since been obtained by other languages.
Clearly not, since most other languages are still not S-expression-based. (Though, admittedly, some other advantages have been copied in other languages.)
