Sorry to punch in here, but:
Roddenberry, who had 3 post-graduate degrees
Meaningless. I almost hate to be the one to point it out, but having multiple degrees doesn't make one any more or less competent. I know university professors who should, quite frankly, just be put to sleep. Just to save humanity from their idiotic fanaticism.
But that's just me.
Now, back to the show.
This is especially true when it comes to writing fiction. In all the years I worked as an editor, I never bought a novel because the author had the right academic credentials. A degree doesn't make anybody a good writer.
(To be fair, academic credentials are sometimes relevant where non-fiction is concerned.)
