'Was' is more likely. The list is from 2003, and if FORTH Inc, the (only? biggest?) remaining forth company hasn't updated it...

Forth is used in firmware and tons of places. There's ANS Forth and no need to 'update' anything, as there are tons of implementations.

As with Lisp, you can bootstrap themselves with very few primitives.

I read a comment on /r/Forth the other day from someone at NASA, implying that Forth was still actively used for something.
