Upvoted simply out of controversy and curiosity. It's been a long time, and I've not delved deeply in to a wide swath of languages (recently), but surely the features he's citing are in other languages? Hell, even the list of "features only Lisp has" keeps shrinking by the decade. Some of these PL/I "features" feel like things you could trivially implement in a library in other languages (ie, not have to implement half of PL/I to get those features). Some of it sounds simply like syntactic sugar, and not actual features. What am I missing here?
