It's fair to criticize aspects that are repeatable, but I still say Siri's "command" ability is easily on par with the competition, if not better.
Siri does resort to web search on super complex questions that are more "meaning of life" sounding, but again, who asks their voice assistant these kinds of questions consistently?
"Give me directions home."
"Text John."
"Set an Appt for me tomorrow at 3pm."
"Set a timer for 30 seconds."
"Wake me up tomorrow at 7am."
These are the functions we use every day. I still don't consistently hear specific examples of Siri failing at these items, which is the entire point of a virtual assistant.
What the heck do Google and Alexa do that's so awesome?
