Siri is sometimes busy doing laundry or Gods know what. I think the quality of Siri is much better than Google Assistant but I wonder about the lag.

Really? I find Siri can’t understand anything slightly more than basic instructions.

Google assistant can seem to do more

I'm very interested in this space. Can you share an example that illustrates the difference in "understanding" between the two?

Just recently Siri would belly-up on “Turn off Living Room lightS” — it would only work if I said “light” (singular). Extremely frustrating. They fixed it, I think, but this arbitrariness and many other make me think Siri is more quirk- and algorithms-based than a true AI.

Handling smart home requests is the one thing that Siri seems to do more or less without error, at least for me. I use that multiple times per day per day, and cannot remember the last time that it did not work.

Is Siri better, or does it have you well trained? My smart home stuff works best for me because I know more of the exact labels. I was literally surprised the other day that my wife included an S and it still worked.

Mine is really really poor at it.

Half the time it responds with "one moment.. One moment.. this is taking too long" or "I have problems connecting to the internet". But there's no internet problems whatsoever and it connects to my home Assistant using local homekit integration which shouldn't even need that.

At this point in time, Siri as a voice-driven assistant has become so totally and utterly useless, its not even worth comparing it to anything else. I wonder how a company can work at a feature like that for 10 years, and manage to make it worse with every release they put out.

At this point in time, Apple should be so embarrased of Siri that I really think scratching the whole thing would have a net benefit.

Scratch it, and start over. And fire everyone involved with Siri :-)

The logistics aren't that easy, Apple's entire product line runs Siri.
