Very confidently wrong.

Do you know why it's easier to specify theorems than it is their proofs? Or why ACSL != C?

You can go ahead and make a more specific argument, e.g. that mainstream UX-centric software development may not be amenable to current paradigms of formal verification, but to insinuate that a complete spec reduces to source code itself is naive.

EDIT: Possibly I have responded too acutely to the points you care less about. I agree that "in the future we won't need programmers" is questionable since good spec-writing and spec-vetting requires at least as much expertise, if not more, than ordinary coding work, and that is fair to call comprehensive spec work "code" in that it is technical and formal. But it is decisively not source code.
