This isn't even an argument. There are waaaaaayyyyyyy more working applications using SQL databases then there are NoSQL at this point in time. NoSQL is the next cool hip whizbang thing, but that doesn't make SQL "dead" by any chance. In fact, I'd say lets revisit this in 10 years, then we can talk. Actually, the more relevant question would be "Is NoSQL dead?" Given that it only holds between 5-20% of the market.
Tech news and marketing is cool, but theres a very real aspect of software where foundations do not frequently change. This is why algorithm, data structure, operating systems, and design pattern books from the 60-80s are still applicable today.
