brother the current 4 year CAGR for bitcoin is 10%... this is just a bullshit chart

USDA Prime Slop incoming, I wrote a paper on this a long time ago so some of this AI slop might be based on me so I can do this guilt-free: People worry quantum computers will ā€œbreak Bitcoin.ā€ Here’s the reality: quantum cannot break SHA-256, not now, not soon, and maybe not ever. Here’s the simple, factual breakdown. Quantum has one relevant trick for hashes: Grover’s algorithm. It speeds up brute-force search from 2²⁵⁶ → 2¹²⁸. Sounds scary until you realize 2¹²⁸ is still astronomically impossible. To run Grover at SHA-256 scale, you need error-corrected logical qubits. Today we have noisy qubits. Breaking SHA-256 requires tens of millions to billions of physical qubits. We have ~1,000. We’re short by a factor of 10,000–1,000,000x Even with the needed qubits, the gate depth (sequential operations) is unrealistically huge. Qubits decohere in milliseconds. Grover for SHA-256 would require years of uninterrupted coherence. Physics says ā€œno.ā€ Error correction isn’t optional—it’s required. Each logical qubit needs 1,000–10,000 physical qubits. This overhead makes SHA-256 attacks physically unbuildable with known architectures. Quantum computers also hit energy and cryogenic limits. Running Grover at this scale would require power levels approaching industrial or nuclear output. Not happening. Why hasn’t someone invented a better quantum attack? Because Grover is provably optimal for hash functions. There is no known or expected algorithmic shortcut. SHA-256 remains quantum-safe for 40–70+ years, and likely forever, based on physics, error rates, and the structure of hash functions. Quantum computers threaten RSA and ECC, not hash functions. SHA-256 is deliberately oversized so even a perfect quantum computer gains no practical advantage. Bitcoin’s ECDSA signatures are the only area quantum could target someday, because Shor can break elliptic curves in theory. But in Bitcoin, your public key stays hidden until you spend, and the attack window is minutes—far too short for any realistic quantum computer. If quantum ever becomes strong enough decades from now, Bitcoin can simply migrate to post-quantum signatures. The hashing layer never needs to change.

if you're already married with kids you just take the inner chaos and confusion and convert it to cancer, heart disease and diabetes.
