Einstein was the paranoid programmer, obsessed with designing the most efficient solution and figuring everything out before writing his code.
On the Java side of the religious divide of programming languages, we laughed at Morts, and we wanted to be Einsteins building frameworks to make sure the Elvises wrote their code the “right way.”
This was the dawn of the age of the frameworks, and unless you were proficient with the latest, greatest object relational mapper and inversion of control framework, you weren’t a proper Java programmer. Libraries grew into frameworks with prescripted architectures. And as these frameworks became technology ecosystems, many of us forgot about the little language that could—Java.
