The "Bitcoin forever" narrative carries a blind spot worth examining. It rests on an assumption that nothing superior will emerge—that innovation stops here. But that's hardly how technology works. When you zoom out, that bet looks increasingly fragile. The real wildcard? Quantum computing. Once that arrives, the entire cryptographic foundation underpinning Bitcoin's security model faces genuine pressure. We're not just talking about incremental improvements; we're talking about potential shifts in what's even computationally viable. The further out you project, the riskier it becomes to treat any current asset class as permanently dominant. Markets evolve. Technologies disrupt. The question isn't whether Bitcoin stays valuable—it's whether tomorrow's computing landscape renders today's assumptions obsolete.
