There are a number of modern Logo languages like NetLogo and so forth, and even older Logos were actually capable of quite a lot more than advertised (Color Logo for the TRS-80 Color Computer even included a chapter teaching recursion!) The trouble is that little teaching with Logo ever goes that far, focusing on a very imperative simple base syntax to make the little turtle move around, and then promptly moves to some other language to teach actual structured programming. A language needs people to grow up and keep using it to survive, and no one grew up just using Logo; they all moved to Basic or JavaScript or Python or Scheme. And since Logo doesn't do anything any other Lisp can't already do, there really wasn't much point with sticking with it.
