That's not accurate.
Rise of the Machines took place after Judgment Day.
Salvation took place prior to the events of everything, it's basically a prequel.
Genisys retconned everything by following up on another fan bitchfest of why not keep sending Terminators to the same time. An additional Terminator was sent to the Terminator timeframe and changed everything from Terminator forward, but it was already changed because humans countered this by sending Arnold to Sarah's childhood to train and protect her.
Dark Fate is the only true reboot that is ignoring the other movies.
Also, I think Dark Fate is gonna be good. Tim Miller, Arnold, James Cameron, Linda Hamilton, Edward Furlong. MY HOPES ARE HIGH. I am more excited about this than Rise of Skywalker.
