Yes, but where would that wisdom come from? Humanity has a nasty habit of repeating it's mistakes and history repeating itself. It is not always accurate but even now in this age where we literally have the history of the whole human race at our fingertips, we're still on the verge of collapse. Humanity is a messy and complicated experiment.
I may not be explaining this well but imagine if you anthropomorphized the entire human race as a single individual. An individual who was born, raised, had a childhood, grew into adulthood, became old, and died. But then snap! Started over as a baby with all the knowledge they had before. I would personally find that horrifying.
Now, imagine if the human race started over all the way back to the beginning. Would we still make the same choices? Would the same people repeat their mistakes? Because that kind of knowledge doesn't necessarily make us immune to mistakes. Immune perhaps to mistakes we've made before, maybe? But what of the mistakes we haven't made yet? We'd still be capable of making whole new ones. Would they even remain with the same people now that they had a second chance? Whole groups of people being born and died would cease to exist simply because they were considered a mistake. A whole new population and history would emerge. Would these new people even continue to value that knowledge? It seems from generation to generation, that that is not true. And why would they continue to value it if they never earned it? Why would they even trust it? And let's just say that they did. Would they still be human? No, I don't think so.
But that's just me taking a simple idea and over complicating it. :)
