Even if your assumption about the trend being to higher levels of abstraction (which is highly questionable) is correct, this doesn&#x27;t give any credence to the prediction that it will make Lisp finally popular. Yes, Lisp is a 4GL but even if everyone is rushing toward 4GL, there are plenty to choose from and it&#x27;s not clear that they will flock toward Lisp.<p>Even if CS is still pretty recent (50+ years), there is still something to be said about a language that never managed to become mainstream in that period. Whether Lisp was ahead of its time is irrelevant. The question is: will there ever be a time where Lisp will be ripe for its time?<p>I think that window closed a while ago. It&#x27;s not about the parentheses or its FP side, it&#x27;s just that the world is moving toward statically typed languages with sophisticated type inference, and it&#x27;s a league that Lisp simply doesn&#x27;t belong to.
