He was referring to Google assistant.

But I can second his point of view from a Siri user standpoint. I use it almost every day for two insignificant task, but yet it work and I use it everyday:

- Shutting down the remaining alarm clocks (I'm really not a morning person)

- Setting up timer when I cook

At some point I also used it to control smart lights but I haven't set up the system again in my new flat. And I'm seriously considering reverting to a purely physical and traditional light-switch interface instead of relying on IoT. (Take ages to set up right, rarely changing setup afterwards, waiting for updates to switch light on, flashlight mode when electronic become damaged, etc).
