“Conversation is the most natural interface there is.” — Charles Cadbury

Charles Cadbury — CEO, Say It Now and Amazon Alexa Cup winner — explores why Voice AI is becoming the new interface for search.

The conversation dives into context windows, ethics, mind-crime, multimodal devices, energy demands, assistant wars, and why voice may replace screens as the dominant interface by 2030.
