The regular (free) Genie seems like it's main goal from a corporate perspective is to spread people out in the park, especially people not that familiar with the parks. From watching that All Ears video, you can tell it what rides you're interested in (but it looked like you can only select up to 8 rides), and/or you can just tell it "I like Star Wars and Princesses" - more general interests.
For instance, in HS I can see it directing people who like Star Wars and don't want to wait for the more popular attractions to go over to Star Tours (hardly a replacement for RotR or Smuggler's), because the programming logic thinks Star Wars + a lower wait="maximizing your fun and minimizing your wait". If you say your family likes Princesses, it will direct people equally to anything involving a princess in whatever park, etc.
Of course Genie will constantly find itself telling people that if you REALLY want to ride RotR instead or Star Tours, and you don't want to wait 100+ minutes to do it, hey, ILL is available for purchase. Or if you don't feel that the Mulan meet & greet in China that it suggested is a suitable replacement for waiting 45 mins to ride Frozen in Norway, hey, buy a ILL for that too.
