No, but again, I'm not talking about a hollywood drama here, this is real life, "collapse" is a thing that exists on a spectrum and can change radically depending on what the political powers do. Nations may restructure, there even may be fighting, but short of an actual nuclear holocaust it's not likely that we're going to see a scorched-earth wasteland.

Everyone on both sides of this are really hyped to the extremes, but there is no telling how the next several decades may pan out, it's not a bad idea to have some ideas that may benefit you, if you think you have better ideas for how to prepare, do share. If you are worried and hopeless and think nothing we do matters, that's obviously not a great mindset to have, we have lifetimes ahead of us and people who are going to make it through, we have a responsibility still to try to do the best we can with what we have.

edit: love that balanced and nuanced takes are making people seeth. Look, just believe whatever you want. The Earth doesn't care and what's going to happen will happen. If you rather believe it's going to be exactly, 100% identical to the Fallout universe and you wanna imagine walking the wasteland, you do you, king.
