When my daughter was studying Chinese, I could use the live-video translation app and see the lesson text translated to English, and see her hand-written answers also translated to English. I could see this being more broadly useful when travelling, along with live translation of spoken words.
I don't know if LLM-based translation is better than previous translation models.
Getting hardware to enable faster AI processing on phones should be good thing if used for useful tasks, LLM or not.
E.g. if it sees that I always reopen an application 2 seconds after the OS kills it in the background, then maybe it shouldn't be killed.
Or if I wake up 3 minutes before the alarm would go off, and take a trip to the toilet, maybe it shouldn't blow up the speaker while I'm frantically pulling up my underpants, but recognize that I'm already awake, or at least wait with the alarm until I'm around the phone again.
Or automatic backlight shouldn't go crazy when I walk in the night under the streetlamps, it should recognize that lamps are coming and going, and that backlight adjustment every 5 seconds is silly and annoying.
I could go on. IMO there is definitely a place for machine learning/AI in phones (and other places too), especially for quality of life thingies. Just nobody is doing them, I guess becacuse these are not as visible as image generation. My credit card has been ready to spend on such developments since at least 2021. One of these days I will have enough of waiting and do it myself, out of spite...
I'd also love to be able to give commands that traverse multiple apps (e.g. take my google sheet and venmo request everyone the specified amount). Most likely this would happen by teaching an AI tool use and having apps expose an API.
I'd love to be able to give voice commands for certain things (e.g. flipping through recipes when my hands are wet) and have the phone be able to do the actual thing I want.
I actually think phones are a much better place for AI since they're so difficult to type on that voice could provide a higher-bandwidth interface.
AI could provide more human-oriented direction that focus on key landmarks and decisions rather than every minor turn. For example:
"Hop on 80 West, cross the bridge, take Sir Francis Drake onto 101 South, take the Alexander Avenue exit, don't go through the tunnel, and your destination will be on the right."
At one point, I had ChatGPT working via voice in CarPlay mode (via Shortcuts I think?), but seems like Apple disabled that at one point, for some stupid reason probably.
Otherwise, totally with you. No idea why my phone needs AI. I can just open the ChatGPT app if I want to have a discussion with ChatGPT about something. I'm so tired of apps updating to "Add a new AI assistant!" like why do I need to talk to an LLM in most of the apps I use?
