I'll be honest with you. My main ask for on device AI is that when I am typing "Going out for a quick j" it corrects to "jog" and not "Jonathan". I don't think it needs that many gigabytes.
The autocomplete of a decade ago is better than what we have now.
It’s harder now because emojis and draw-to-type as well as pen input. We didn’t have these things 14 years ago when “I’ll be right back” could be expanded from “I’ll b ri ba”
But seriously, wouldn't productive text on a 90s cell phone pass this test?
