Has that actually been confirmed somewhere? I've not seen a post indicating that the rewind we saw in the last episode is a complete reset. Did Adam post that somewhere?I've read through many of the Reddit posts surrounding the final episode and have not seen that confirmed. There were several pointed questions asking in the episode 50 Q&A and Adam purposely did not confirm. was it a reset or did we just play out a dimensional shift in the lest few episodes. As he has said before "Killing us is the least interesting thing he can do, he wants to make us suffer!"
Adam also said in that same Q&A,"I think it's interesting how linearly everyone is seeing that "rewind". It, like so much of the last few episodes, was metaphorical. What we'll see when we come back is very much up in the air..."
Certainly there would be some changes in the verse if there was a time shift giving Higgs a different choice with Randy". However, that doesn't mean a complete wipe, that "rewind" scene could of just been Adam giving us a visual(with some trolling to leave us guessing) of the universe putting itself back together again after Steven's double 1's destroyed it. Many of the primary story arcs could still be left intact. IF there were to be any changes they could of very well have occurred in a Eureka(the show) style effect. There we several statements inside Shindalien Valhalla that indicate that things were not complete....
Shindalien Viktor speak to Piani and says to her, "We put the child in your care and you've done a such fine job so far, but the hardest is still to come. The weapons needs to be stopped."
Previous to that, Shidalien Viktor tells the Erik and the Paini stand in something to the fact of... things were let out and we couldn't put them back in. After which Shindalain Viktor states,"you may not understand what we are trying to do"
All of this indicates that there is still work left to be done on that front. There is also a few statements earlier in the show point towards the attempted bridging between AI and MES. IIRC the Warmind was even trying to bridge that gap. Perhaps because they know that if they could that would allow them to remain intact through a reality swap or whatever you want to call it.
In the end of it all I would like to see a return to Swan Song
