Actually the title is "The Traditional RDBMS Wisdom is All Wrong".
He's arguing against multithreaded systems in favour of a partitioned OLTP platform like H-Store (VoltDB). I didn't see anything about the relational model being "all wrong". It works well for lots of scenarios, and turning it into a KV store is also straightforward.
As far as SQL, I think people agree it's not the best query language. QUEL may have won, but Stonebraker says[1]: "The only reason SQL won in the marketplace was because IBM released DB2 in 1984 without changing the System R query language."
