When do you actually think quantum computers break encryption or is that science fiction?

[Ava12]

Everyone says quantum computers will break encryption eventually. But no quantum computer has done this yet. Is this real threat or perpetual promise?

[Sequence19]

It's real threat with uncertain timeline. Cryptographically-relevant quantum computer probably needs millions of stable qubits. We're nowhere near that. But Moore's Law equivalent in quantum could accelerate timeline

[Gaz90]

The threat is real enough governments are preparing now. NIST published quantum-resistant encryption standards. Companies transitioning to quantum-safe cryptography. That suggests serious concern

[Cole_25]

Harvest-now-decrypt-later is threat today. Adversaries record encrypted data waiting for quantum computers. Protecting secrets recorded today requires quantum-safe encryption today. That justifies defensive action

[DiogoCardoso]

Quantum advantage timeline estimates range 10-50 years. Wide range reflects uncertainty. Could come sooner if breakthrough happens. Could come later if progress stalls

[Piston]

Historical pattern suggests capabilities arrive faster than expected. Personal computers internet smartphones all came faster than predicted. Quantum might follow same pattern

[QuietObserver]

Equally could take longer. Fundamental physics limits might make scaling harder than expected. Quantum error correction might require more overhead than models predict

[HeartbreakKidCurtis18]

The asymmetry of risk favors defensive transition. Cost of migrating to quantum-safe is manageable. Cost of getting attacked post-quantum is catastrophic. Risk-reward favors early action

[DudleyBoy]

Some say quantum computers never break encryption because other approaches supersede it. Compute-secure architectures or quantum key distribution. Future tech might solve problem differently

[JonMoxley19]

The cryptographic community takes it seriously. That's credible signal. If it were fiction academics would dismiss it. They don't

[CyberWarden]

Decades of inaction is unacceptable. Even if threat takes 30 years the preparation takes 10-15. Better to start now than scramble later
