I think it can be saved. It may never be perfect again, but since there's no highly localized bend, a decent wheelman should be able to true it back up. I've seen lots worse brought back to where you'd never know it was ever damaged.

Usually this kind of bending is caused by large side forces. We see lots of here in the Northeast in the fall when there are leaves on the ground. The rbike will start to slide on leaves, then when the leaves wear through the tire bites causing a sizable side force. I t can also happen when you slide on ice or sand, and bite on coming to dry pavement.

No fun, but part of the game.
