Sorry, Joz, I call B.S.
I wish they would have an "Apple Maps moment" and admit that Siri is subpar and say that they are committed to doing better. I don't care what Siri sounds like. Making it sound like a "trusted person" isn't important to me. I just want Siri to understand what I'm asking it to do and then follow through and do what I've asked it to do damn near 100% of the time.
More than half the time, Siri misunderstands me when I tell it to turn a light on or off. If I say, "Turn x light on" it will hear "Turn x light off" and vice-versa. Also, as I've mentioned in previous posts on MR, I can't have two rooms in my house that start with the same letter for HomeKit purposes (i.e. Family Room, Front Room) because most of the time, I'd ask Siri to turn a light off in the front room and it would alter my family room lights and vice-versa.
These examples have nothing to do with asking Siri 'Trivial Pursuit' questions. This is the stuff Siri was supposedly engineered to do and its reliability in these areas, in my experience, leaves much to be desired. And here they're aiming to make Siri sound like more of a "trusted person". Sorry, Joz, Siri is only great when I can rely on it to do what I've asked it to do. It sounds to me like Siri won't be improving much anytime soon, unfortunately.
