I think they're equating relation database with databases with ACID guarantees, as thats basically a full overlap on a venn diagram. And we all know that acid has to go at some scale, even if that scale keeps getting pushed further out as our hardware gets better. (Same with the relational guarantees that eat performance... But only once you've reached a certain amount of throughput and data)
