Who has an interest in considering a benchmark on a 64-qubit system as sufficient proof for large-scale investment decisions? The gain for researchers is academic validation, but for a hedge fund manager, it's risk-adjusted performance.
If everyone relies on small-scale benchmarks, the risk of a false positive becomes high, because incentives are misaligned between proof of concept and practical application.
For example, an optimized portfolio in the laboratory without considering transaction costs or market liquidity for thousands of assets would lead to a significant defection of the strategy in real-world conditions.
