I use Siri and Alexa almost daily. I feel like we have a very long way to go.
Now if you are doing a tech radio show, this has a high entertainment value. If you are busy, in the middle of something and need a task done, these repeated failed interactions are a complete non starter. Imagine a smartphone where the screen wouldn’t register a tap half of the time, it would end up in a bin very quickly.
Plus I am not sold on non self-discoverable UIs. Like I don’t remember the name of all the operas I have on my phone. It takes seconds to browse with a screen. Same things for the commands. If forcing users to learn by heart dozens of commands was commercially viable, we would still be using MS DOS! But GUIs are way more powerfull.
