To understand how the pioneer of smartphone voice assistants became a frequent target of criticism, one must look at the underlying architecture that governed Siri for more than a decade.
Users view tools like Siri differently than standard software. Voice assistants are designed to mimic human interaction, adopting a personality, name, and voice. Because users anthropomorphize these systems, a failure feels less like a broken tool and more like a personal betrayal or an insult from a trusted entity.
