Buddy of mine pivoted to doing just SQL and road into retirement as a DBA.
With hindsight, we both wished we had gone all-in on SQL way back when.
On my 50s, learnt SQL around 1996, have used SQL across Access, Informix, DB2, Sybase SQL Server, MS SQL Server, Oracle, MySQL, Postgres, PrestoDB, Neo4j.
I spent 2 years coding in ColdFusion maybe 25 years ago. I've got experience!
