Sci-fi films are a great way for creative folks to predict what might happen in the future, using evidence from what is going on right now. With that in mind, knowing what is evident on TikTok, let’s hope “Voyagers” is a cautionary tale for why we don’t entrust the future of the human race on a bunch of hormonal teens. (I’m only partially joking because that makes me sound incredibly old, but also, have you seen TikTok? I’ve seen enough cringe on that app to become worried about the future of our species.)
