Also, I'd like to point out that no other prophecies in the show have been proven wrong.

Aithusa didn't prove to be a good omen for the world Arthur and Merlin would build together, she was instrumental in causing Arthur's death. Morgana didn't restore the Old Ways. Arthur never united Albion - and the prophecy was that he was the one who would do this, not Merlin or Guinevere - and he never distinguished himself as a great king.

I'd say that the show was a good lesson about the folly of putting one's faith in prophecy.
