Whenever Lisp's history is mentioned we get another free replay of this classic "who's on first" bit:

A: Lisp didn't succeed in part because it was slow

B: What? Lisp isn't slow!

Do you see the problem? No, it isn't slow now, but it was slow and a resource hog and that is a legitimate variable that may have negatively affected uptake during key points in its history. Times have changed, implementations have improved, resources have become less scarce, but the past is still the past.
