One of the most useful relatively straight forward things I want to ask an AI assistant "at what time does this store/restaurant close?" Siri fails colossally.
You dare to tell me in 5 years no one could improve the assistant to give me the time a store closes?
Google now works fine with that query for example.
I could go on with pages of criticism, my point is Siri is utterly and completely stagnant for most of its lifespan. Little tweaks and improvements are absolutely marginal.
I just tried that request with Siri on a random sample of five different stores. It got every one right, including one open for 24 hours.
