+> No one really knows how anything works in a modern computer.

+Also - There is always a critical perl script somewhere that no one understands. I joined a pure Micrsoft, 100% (it wasn't) .Net shop with 25 years of Microsoft solutions on Internet Information Services, with MSSQL databases.
+
+When I brought code inventory to the organization, there was a critical perl script.

+
+So what can we do about that?
