So I saw this on reddit:
If that's true, then these writers are even more retarded than anyone could have possibly thought. Picard went back in time to before the divergence. Therefore at that point, his future self has and has not come back in time, its a superposition of his actions, which collapse when the divergence happens/doesn't happen. Except this makes no sense as the event is in the past, therefore it must have happened, and Guinan should have already known Picard.
Also, supposedly the 2024 is supposed to track Trek timeline, so that they're not in present day real Earth. 2024 Star Trek universe is on the path to World War III (it starts in 2026) and like only 30 years past the eugenics wars which killed tens of millions. So politically and socially, it's not current day Earth. If this is what the writers were thinking, then maybe some dialogue to explain to the audience this was the case would have been beneficial. It would only have taken a couple of lines before they left the ship.
"Remember, the eugenics wars occurred 30 years ago, tensions are high on Earth in the lead-up to WW3, x, and y are the things that will trigger it, we need to not alter the timeline, rather restore it so don't do anything to cause z.
I mean its not that fucking hard, yet these dipshits can't do it. I have to ask, isn't destroying the cultural legacy of a society a crime against humanity? If so, these fuckwits are clearly committing crimes against humanity. I demand they be put on trial in The Hague.
