 The field is also much younger and messier than the hype suggests. Today's hardware is noisy, error-prone, and limited to hundreds or a few thousand qubits. Running any of the famous algorithms at a useful scale requires fault tolerance, which in turn requires encoding each logical qubit into hundreds of physical ones. That gap between what quantum computers can do in theory and what they can do right now is the central engineering problem of the field. The field is also much younger and messier than the hype suggests.
