Vitalik Buterin Backs Crypto ‘Bunker Mode’ as AI Threatens Private Keys

The shift here is about timing, not technology: the warning targets AI-driven math advances rather than the long-discussed quantum threat, which changes the urgency calculus for every self-custody holder.

Whether this stays a researcher-led hygiene push or becomes a broader migration norm is the open question, and how wallet providers respond will matter more than the guidance itself.
