Yet every single person uses an AI assistant every day when they Google something or ask their phone for who performs the song that's playing in the background. You must know some of these people?
I don’t think that I would call every AI feature an AI Assistant, but sure, if that’s how you define “AI Assistant,” then you’re correct that I do in fact know people who use/want one. But I think that Google+AI or a music player is a pretty different product experience/design/market fit than a “personal AI Assistant” like an AI-powered Siri or Alexa or Google Assistant. I don’t know anyone who uses (or wants to use) the latter group for anything other than “Alexa, play XYZ”, or “Siri, set an alarm” which I wouldn’t really call GPT-4-level AI
Just because LLMs only really existed for a year now and it's still the fastest adopted new tech we ever had. Even iphone took longer to adopt. It'll take time for LLMs to lodge into direct use and thus the move to voice chat by openAI but every single person is already full in AI game from photo editing, to content curation - AI assists us everywhere already. The leap between that and texting to an AI friend is extremely tiny.
