You seem to define the reason as purely historical. Kinda like how Linux was going to take over the desktop "any year now" and it hasn't. Yet Linux is everywhere people don't think it is. It's on most of the world's smartphones, for instance but people still consider it "failed". I think Lisp is the same: it's everywhere you don't think it is because it's opinionless and languages are defined by their community (and community is held together by the shared values and opinions). Look how many languages are rapidly adopting functional programming idioms. They're becoming Lisp. Eventually you start seeing the value of functional idioms in Blub language. Then you go and look at where it came from and notice, "Hey this is the real thing". Then you get real yourself. (This has been my experience).
