" summary

Argues that real-world data dramatically changes computational hardness: starting from an easy Hartree‑Fock circuit and adding interaction layers produces BQP‑hard instances, yet supplying only a quadratic amount of classical data collapses the task to a trivial regression; formal work shows a classical learner with such data (BPP^SAM‑style) can solve problems previously thought to require quantum resources. Proposes multi‑qubit quantum sensors and state transduction as the route to exponential sample advantages, and flags chemical synthesizability as often undecidable without empirical advice.
