But Lisp is faster than almost every widely used language that's not C/C++/Rust, around Java speed.

Dunno, by modern standards it seems pretty small.

Ish. Because it's so mature, lots of code works even it it's not updated constantly. There's code out there for most use cases, at least for back-end-y things.

So enforce coding standards. This isn't a negative and lots of us work alone or in small teams.
Honestly, the only reason I don't mainly use Lisp is because I use an even slower/easier language because I don't really need a performant language. But if I find a problem where I want more performance Lisp is probably the next stop.
