Note that Stonebraker intends no praise of SQL as a language here.  He
is merely admitting its undeniable dominance of the market.  The
"intergalactic data speak" quip is from the Third Generation DBMS
manifesto, cited below.

I'm not aware that "most academics" feel that QUEL is superior to SQL.
It's simpler and hence closer to the relational algebra, but it's also
not as powerful as SQL (no subqueries, no duplicate semantics, etc.)
