One thing is for sure, Gene was totally out of touch with reality during the making of the TNG. That seems to be the theme. I have no problem with that because Trek was usually at it's best when Gene wasn't directly involved. He also turned into a flaming lib during TNG and it shows some times, just wrecking the show. Same happened with Lucas when he totally sucked the mystic / mythical elements out of Star Wars with the prequels. Gene's whole vision of man wouldn't have conflict with one another is just unrealistic and insane. It ignores history. It also made for crappy storytelling.
That's kind of what "hope for the future" means, though. I had no problems with the "conflict from the outside" concept Gene had that makes for more creative story telling if you ask me.
It's easy to have the crew bickering and fighting with one another, it's not easy and more creative to have conflict come from other places.
