Ok, after reading it again, by "very clear" I was overstating it, but there is this note:

And in no place he says Lisp is the end-all best language. At most he compares it with other languages his competitors used on the context of Viaweb, what on the bottom of the article means C++, Java, Perl and Python.

He indeed goes on to argue that any language more powerful than Lisp would be Lisp, because macros work that way. If you don't take notice that he is simplifying things into a power continuum to make a point, that can mislead you into the message that Lisp is the most powerful language. But he puts some effort into making the message language agnostic.

Is Forth Lisp? Given that you can control the reader, everything is possible syntactically, and semantics is entirely what you make it.

I would say it fits his description (but well, I'm also quick to dismiss it all because ergonomics matter), so it's at least equivalent in power. I have no idea what he would say, I imagine a serious lisper would be offended by the suggestion (because, well, ergonomics matter), but would take a while to even understand why.

Curiously, it did come up in the context of ergonomics in another discussion thread:
