Any of the recent LLMs can blow away the commercial voice assistants we have today. But why are voice assistants so primitive? It's probably too expensive to give everyone GPT-3 powers in their speaker, but that should change fast because they have models 50x smaller with comparable quality.

But probably that was not the only reason LLMs are not in voice assistants, I bet they are afraid it will be prompted into saying racist things and make bad PR. Who wants a 'MS Tay' on their hands?
