I must disagree. ChatGPT-style LLM functionality with ElevenLabs-quality realtime voice synthesis will absolutely supercharge these products. The ability to e.g. answer kids' questions in simplified English according to parental prompt guidelines, or drill down on complex educational topics, or maintain context over many back-and-forth conversational interactions will be huge.
