nvk published one of the most important pieces of Bitcoin content this year. He's mostly right. The quantum computing industry is running a spectacular marketing campaign on $40 billion of government money. The timelines are garbage. The VIC-20 joke is real.

And yet. Bitcoin still needs to upgrade its cryptography. These two things are not in conflict.

The argument isn't "quantum computers are 5 years away." It's "a $2 trillion network shouldn't depend on a single cryptographic assumption — especially one that Bitcoin's MOST RECENT upgrade made harder to fix."

Taproot exposes tweaked public keys on-chain. 6.26 million BTC with exposed keys. 30-35% of supply. Our last major upgrade made the quantum problem worse — not because it was wrong, it wasn't — but because the migration path now requires governance decisions we haven't made yet.

nvk's own words buried in Part 6: "Because relying on a single cryptographic assumption for a $2 trillion network is bad engineering."

That's the whole case. No quantum hype required.
