To illustrate the difference look at C++, it was designed by a person with strong opinions, but then left it to be controlled by a committee.
If you look at the structure of C++ in Backus Naur form it is absolutely nuts. The compile times have gone through the roof and people leave to create new languages like jai, Zig or whatever.
Common Lisp was designed by committee. It is as chaotic as C++.
Rust is also gigantic. I am very careful not to use in critical systems because it is so big unless we could restrict it with the compiler or something.
