I thought this was about me.

I learned SQL 30 years ago and, well, pretty much stopped.

Through the years, as we added ORMs and were using the databases more for base dumb storage, and that I ventured away from report writing, focuses more and just services, workflow and CRUD, I never really learned modern SQL. I've just been able to muddle through with the SQL I learned long ago.

To the articles other point, I've been doing Java for almost 30 years, and while we have a much more modern language, the fundamentals of years ago are still sound and used every day.
