Original Answer

If humans will eventually achieve immortality, what will the final world be like? Why will high-dimensional civilization stop imparting more advanced knowledge to humans? Can you believe what a mental patient says? If the so-called parallel universe and time travel are just save and read files on different data "servers" in the eyes of high-dimensional civilization, then what should be the ultimate goal of human development? I hope that "The First Answer" can bring you an experience and thinking that is different from traditional Western science fiction stories.
