Considering the Didact isn't even supposed to be evil or any kind of villain whatsoever (seriously, 343i making him evil (I could have [i]maybe[/i] forgiven them if they'd made him a [i][b][u]GOOD[/u][/b][/i] and he was well-written and believable and actually had depth, but instead he's just your usual generic, card-board cutout cartoony villain with all the depth of a puddle) is like having Yoda suddenly be the next villain in Star Wars, or finding out that Gandalf was secretly evil all along....it just doesn't work) and he and Noble Team wouldn't ever be fighting if things were kept how they're supposed to be... But in any case, if there [i]was[/i] a fight, like with [i]most[/i] Forerunner technologies or actual living Forerunners, pretty much everything in the current era of Halo would lose, and lose badly at that.
