Many ideas that come from lisp, and for which lisp was long ridiculed, are now mainstream, like garbage collection, closures, a big runtime, a huge library (nowadays lisp is criticised for its small library), typed data (instead of typed storage), exploratory development in an interpreter coupled with an optional compiler...
I don't consider languages with these features lisps, but I think the GP's statement is only quite mildly hyperbolic.
That's not a revival of lisp itself, just it's ideas becoming pulled into more mainstream languages. I wouldn't call Python having a REPL to be a lisp revival, but you can disagree.
