This is part of the mismatch between comparing Alexa/Siri/Cortana to a chat based LLM right now. If you just want chat and info retrieval, today’s LLMs are way better then the conversational dialogue, search, and q&a capabilities any of those assistants have. But, if you want relatively predicable task completion for things like smart home control, timers and alarms, real time weather updates, etc. (basic but frequently used interactions) or any integration with your phone or computer directly, there’s a lot to do that isn’t solved yet in the LLM space and is more of a system integration and action choice problem that the existing assistants have been hammering away at for years.
