> Code (and specs) are going to fade into obscurity

I'm always skeptical when I read absolute statements like this.

Especially about specs. They drive and document how the software should work, behave, and under which conditions. In the same moment you write a prompt in natural language, you are writing a spec.

Why should they disappear?

For the same reasoning, we could no longer need books or manuals or documents (is it valuable to keep around that doc about F-22 specs?).
