That said Siri feels at least 100 times smarter than Google assistant to me, the below are actual (if somewhat anonymized) examples:
- Google suggestions when I look at the phone at 5am in the morning: "text random friend of a friend that I answered a question for over Telegram" or "call customers project manager". See https://erik.itland.no/tag:aifails for screenshots and more examples. In the years I had access to the future it maybe helped me twice by pointing out it was time to leave for an appointment.
- Siri suggestions are mostly mundane (more or less predictably tells me when to leave for appointments, kids soccer and hockey training etc, suggests picking up kids at kindergarden - although not consistently, suggests sending messages to my wife over our preferred messaging solution, tweeting, or if I drive 5 minutes down to the shopping center: that I should drive home the way I always do etc) but I have never caught it suggesting outright idiotic things like Google, and once this weekend it even suggested something semi-smart (a text message to my wife that was surprisingly close to one I could have written myself to tell her I was on my way home, including one of my rather unusual abbreviations and with good timing :-)
