I really don't get where this kind of factually incorrect griping (hate?) comes from. Siri HAS improved significantly, and I know because I've been a user since it came out. New functionalities have been documented constantly on this and other sites. You claim it was DOA the day it came out and that you stopped using it. How can you know whether or not it has improved if you don't use it?
It can be taken seriously. It is useful. It is not 100% effective and correct in its responses, but the accuracy and flexibility has improved considerably over the years I've been using it. Sure, I wish it were more accurate, and want it to do more, but that doesn't mean it IS and always WILL BE of ZERO UTILITY.
I don't use a single piece of software or technology that doesn't crash or freeze up or glitch occasionally. But Siri seriously crossed over to significant utility years ago. Things I find of great utility and that are part of my daily routines include;
- quick math and unit conversions
- scheduling calendar events
- adding things to my shopping list
- opening apps
- controlling music and podcast playback (love to "skip ahead 90 seconds" to avoid ads)
- responding to texts (esp. hands-free in the car over my bluetooth system)
- Homekit control of my devices (it and Alexa are roughly equiv. in utility and I use them interchangeably)
- getting navigation guidance on the road
- looking up random information (something like an 70-80% hit rate of finding what I am looking for)
I suppose the fact that I have a Ph.D in physics, work at Caltech, and have followed technology my whole life can be rendered irrelevant (I "can't be taken seriously") because I've come to a different conclusion about a technology you don't like.
