This is justified. Good development (my opinion) iteratively transcribes skills and methods into code so it can become more widely available. People naturally, then, move onto other things and either forget or never bother to learn those skills. It is liberating, because with a calculator or spreadsheet almost anyone can do complex calculations, but it also makes us dependent on our tools.
But we are dependent on our tools for civilization. Somebody, somewhere, knows how to capture their special knowledge in an artifact and share it with the rest of us, and we're all better off. Someone made every article of clothing I'm wearing, and it wasn't me, but there's no risk that we, as a civilization, will forget how to sew although I am concerned there's nobody left in the USA that sews.
