Smart devices since iPhone have been lacking so far.
iPhone hasn't yet been outdone in terms of how big of a shift it introduced toward smart devices. Most of the later attempts have been lackluster, and voice assistants stand out as a great example. After 10+ years since their start, I'd summarize voice assistants as “UI upgrade alone being sold as a paradigm-shift, while providing minimal improvements to the underlying capability.” The underlying intelligence never matched the interface's promise.
But With LLMs, we are at another iPhone-style inflection point. LLMs have surpassed voice assistants in terms of capability (especially the capability potential), but they are currently fronted by simple UIs. The time is now ripe for an authentic and substantial UI upgrade. We may soon have portal and peronaslized LLM devices. Something along of the lines of what Humane Pin set out to do. A very striking example, although fictional, would be from the film 'Her'.
