Well fortunately for all of us the people delivering client side ML today are totally different from the people who implemented a server side rule base assistant 10 years ago.
The fact that they couldn’t deliver something even approaching kindergarten levels of understanding a year ago makes me worry that either zero of the people who know what they’re doing in present-day “AI” work at Apple, or, plenty of great minds do but they can’t get anything done because Apple’s management is too conservative to release something that would be vastly more powerful than Siri but might possibly under certain circumstances hurt someone’s feelings or otherwise embarrass Apple.
Nothing would make me happier than to finally be wrong betting against “Siri,” though.
