Dear god No. People are already entirely too vapid and reliant on the internet as it stands.
Seriously. If you have lived in a city long enough to tell someone to meet you in front of X bookstore and buy tickets for some random indie artist playing at a club that you are familiar with its a pretty safe bet you wont need directions to it or detour directions to the bookstore, nor would you need a internal layout map of the bookstore because youve likely been in there before.
Another thing of this.. Is this sets the stage for massive fan letdown, because its a guarantee this will not work in any way shape or form like or as fast as what this video portrays, leading in ME3 ending retalliation when people are unsatisfied with the product and end up making Siri like lawsuits.
This is truly TRULY a bad idea.
EDIT: Also, let us not forget. That this video only shows you the hypothetically functional portions of this. It does not show you what you absolutely KNOW will be there as in forced advertisements and popups trying to sell you even more inane crap you dont need.
Other thought: How fast would laws be put into place restricting where this could be used, specifically while driving, operating heavy machinery, etc
