SQL isn't obsolete, but it's awfully tiring to deal with folks who treat it as the end-all be-all of data tech. The project I'm working on right now has a few dozen stored procedures stapled on to a Hadoop cluster because none of the industry veterans trust this new-fangled "Spark" technology. When the quarterly schema changes come around, the entire environment has to be redone so as to accommodate the hard-coded SSIS ingestion pipeline.
