Summary
The author critiques the QDay Prize competition, highlighting predictable failure due to the current limitations of quantum computing and Shor's algorithm. While the prize aims to incentivize progress, the technical realities and hype surrounding quantum computing make such competitions seem impractical. The post reflects on the intersection of theoretical potential and current technological capabilities in the quantum realm.
