Current limitations, stated plainly

Today's quantum computers are noisy, small and specialized. They do not "try every answer at once," they cannot break modern encryption yet, and most commercial "quantum" claims deserve scrutiny. The field is real and advancing fast — precisely why it deserves honest coverage.
