In terms of practical usage, FYI both bitcoin script and postscript (for printers) are Forth based, as are some aerospace chips.

It’s arguable how much, if any, Forth is in PostScript. It is, indeed, a stack based language, but that’s pretty much where the similarities end.

There’s more to what makes a Forth a Forth than a parameter stack.
