Logo was designed to be a children’s language, so the direction of causality between it being regarded as a “kid’s language” and its association with schools and turtles goes the other way! It used a turtle because Wally Feurzeig, Cynthia Solomon, and Seymour Papert thought this was a good device for teaching about geometry, and Logo was associated with schools (and Lego!!!) because they were trying to change education. https://en.m.wikipedia.org/wiki/Logo_(programming_language) https://en.m.wikipedia.org/wiki/Logo_(programming_language) Of course, you are also right in that once it has momentum along these lines, people tend to put it in a little box marked “children’s language” and not build on it in a more general-purpose language direction. A few folks have tried, but like squeak and pharos and so many other dialects of Lisp and Smalltalk, it has never gained serious traction outside of its original purpose.
