Google AI try to match people to information hopefully so you get the information most relevant to you.
What happens when google AI and Google Arcadia marry.
So your walking through a show room using google AI.
Your shown try before you buy exhibits with pre ordering if that's what you like.
When a crowd is asking questions across the cloud to the person holding the lecture the AI filters each time from the bag of asked questions in that session down to one question to ask this host.
In the exhibits you can learn new things about what you already own. Each game or game series has a launch pad on the phone or bigger device. content can be deduced for a launchpad or back to the main exhibit in the show room which a good gpu phone could act as VRish without the goggles.
The same games run on all your main devices.
This is the sort of thing where having 5G is good.
