How long before these vacuous AI assistants will be useful in the real world?

* "Siri, check if there are better deals than renewing my car insurance with current provider."

* "Cortana, book my brother a flight from Milan to Toulouse on Monday, and don't forget to check budget airlines that aren't on expedia."

* "Alexa, change my phone contract to the new daysaver tariff."

Telling me it's raining outside or being able to make a restaurant booking in a handful of places in NYC is just not interesting^W AI.

Context and identity seem to be major missing ingredients.
