This is a good point. I started with Turbo Pascal in school and my first job was writing VB 5 Windows apps for local businesses. SQL (and C, but I haven't written it in ages) is probably the only thing I learned in the late 90s that has been a constant my entire career. Languages and frameworks seemed to change so frequently that I never thought too much about them. I was always focused on the end goal of solving some business problem.
