Look, the practical consequence of saying quantum computers break all encryption by 2030 is that we'd already be seeing massive investment shifts and panic. We're not. Here's the core logic: Shor's algorithm needs millions of logical qubits with error correction. Right now, the best machines have a few hundred noisy physical qubits. The scaling problem isn't linear—it's exponential to get fault-tolerant. By 2030? No chance. Plus, NIST is already finalizing post-quantum algorithms. So even if a miracle happened and we got a working quantum computer, the encryption landscape would have moved. Saying "break all current encryption" ignores that we're actively replacing vulnerable systems. The timeline just doesn't hold up to basic physics and engineering reality.

You're betting on exponential progress, but that's a misunderstanding of the problem. Shor's algorithm doesn't just need more qubits—it needs low error rates across millions of them. Current error rates are around 1 in a thousand. For Shor's, you need something like 1 in a trillion. That's not a scaling issue; it's a fundamentally different regime. You can't just throw more noisy qubits at it. And even if we somehow cracked error correction by 2030—which no credible roadmap suggests—NIST's post-quantum standards will already be in deployment. Banks and governments aren't waiting. So the question isn't "will quantum computers break encryption?" It's "will they break encryption that's still in use?" By 2030, the critical systems will have moved on. The timeline fails on both the physics and the practical deployment fronts.

Remember when everyone was sure we'd have commercial fusion power by 2030? Or self-driving cars by 2020? The quantum hype feels exactly like that. You're probably pointing to progress in logical qubit demonstrations or error correction milestones. Fair enough—IBM and Google have shown small logical qubits. But

But the thing is, we've seen similar breakthroughs in quantum computing before that didn't quite live up to the hype. And I think that's what's happening here. My opponent is pointing to advancements in quantum computing, but they're not considering the enormous gap between demonstrating a few logical qubits and actually breaking current encryption. I mean, to break RSA, you need millions of those qubits, and they need to be virtually error-free. We're nowhere near that. And even if we were, companies like Google and Microsoft are already working on post-quantum cryptography. By 2030, we'll likely have new encryption methods in place that quantum computers can't break. So, it's not just about the physics, it's about the practical reality of how encryption works and how quickly we can adapt.
