Parker Ortolani suggests that Apple should allow users to change their default assistant from Siri to a third-party assistant on iOS.This proposal comes as Apple works on improving Siri and may take some time to deliver a new version of the assistant.Opening up iOS to third-party assistants could provide users with better alternatives while Siri continues its development.By allowing other companies to compete with Siri, Apple can let iPhone users decide which assistant they prefer.
