One of the clearest signs that modern secular elite culture is uneasy about death is how Silicon Valley talks about it. The human body is treated like legacy hardware waiting for an upgrade. In place of acceptance, you get optimization: longevity startups, cryonics, extreme biohacking, and constant speculation about whether enough computation and biotech might eventually defeat death itself. Tech billionaires talk with pride about potentially transferring their consciousness to a computer, as if that wouldn't just be a copy at most of yourself. That is ego, believing that you're so great and important that a copy of yourself is needed to live for all eternity overseeing humans...
None of this is inherently evil. Medicine saving lives is obviously good. The issue is the emotional posture underneath it, where death stops being a fact of human existence and starts being framed as an unacceptable design flaw.
For most of human history, religion provided a different framework. Christianity did not deny death or romanticize it; it treated it as real, final, and morally significant, while giving people language for grief, hope, and meaning inside that reality. Death was not something to “solve,” but something to face. Resurrection is a miracle that only God can perform. Death is a mystery to all of us and what happens after is not for us to know.
You can see this in transhumanist thinking and simulation theory alike. One treats consciousness as information that might be uploaded. The other treats reality itself as something that might be escaped or rewritten. Both carry the same instinct: mortality feels intolerable, therefore it must be technically defeatable. The need for a trascendental reality is still there, just masked behind tech and software terminology, rather than traditional religious terms. You can't be an atheist and believe in Simulation theory at the same time. If we live in a Simulation, that is pretty much Theism with poor and basic theology. Instead of a God, you have unknowable, super-dimensional beings that created our universe through computation.
