This is a serious question that's partially mine, but I'm asking because of all the comments here: Specifically, what HAS Apple done with Siri over 15 years?

Are there new functions I don't know about? I... can't think of anything else they'd add, but I literally do not understand what their engineers and managers working on Siri were doing on a daily basis. They must have been writing some code at some point. Did it just never launch? Am I simply ignorant?

They changed it from responding to "Hey Siri" to just "Siri".
