Quantum Computing Will Replace Classical Computers Imminently

Quantum computing will replace classical computers imminently, but current hardware solves only 1 in 10,000 arbitrary problems, as shown by the 2023 IBM Heron processor benchmarks. The largest publicly accessible quantum system operates at just 1,121 qubits, yet error correction requires thousands for any practical advantage — meaning a modern laptop outstrips it for standard 64-bit calculations by a factor of 10^15. This exaggerated timeline massively underperforms the #9 cold fusion hype, which at least has reproducible lab anomalies; here, the gap between press coverage and capability is 30% wider. A 2022 McKinsey report projects general-purpose quantum advantage at least 15 years away, while $1.8 billion in 2023 venture funding poured into a field whose best algorithm can factor 21 (3×7). For now, quantum remains a specialist tool, not a replacement.
