It's always bugged me when professors go on about recursive processes because they're saying outright that you can add on and on not just to infinity but to "multiple orders of infinity". This may be true of a computer program designed to generate theoretically possible sentences in a given language, but it's not true of real human language production. You can't add 600 adjectives onto a noun; we have limits on that sort of thing. You can't embed one clause inside another until the cows come home. You can do just this sort of thing in programming languages, but not in human language. Just one of the many ways the human brain is not like a computer.
