Nobody has released a single piece of AI specific hardware that has an answer to the question "What problem does this solve that a phone couldn't do?"

I struggle to even imagine what that device would do. They talk about essentially adding sensors to the AI's perception around you and doing stuff for you. What daily problems do people have that AI can help? As far as I'm aware most people use AI as a glorified search engine.

Ignoring the privacy concerns there, this device just sounds like an extension to your current smartphone, which is in no way a groundbreaking product. The only way it ends the smartphone centric world is if this new form factor also replaced content consumption, which would just be AR glasses, and we are quite a way from technology making those feasible for replacing a smartphone and being usable for a full day.
