So, this is a sort of "World of Tomorrow" convention we're attending? Where it's just a bunch of inventions being shown and people throwing money at them, or are they just sort of there and this is a convention for something else?

Pretty much it's a convention run by the people who made this technology, proving that it's worked over the last several years. They're also hyping it up, and announcing their technologies so they can be sold and such.
