That's a colorful-but-accurate example of some of the challenges VR developers are facing right now with room-scale tracking. Casey, immersed in the world of the pin, cracks her head on several walls, falls down a flight of stairs, and wanders into a lake. Speaking of that pin, it might just be because I've spent the last week experimenting with VR locomotion strategies, but the virtual reality of the pin feels weirdly spot-on. Watching the film, I couldn't help but wonder what the protagonists think of SpaceX.

The VR 'commercial' for Tomorrowland that Casey encounters via the pin (featured heavily in the trailers) ends with the viewer climbing aboard a spaceship, bound for a destination "20 light-years away" - perhaps Gliese 581, a potentially-habitable exoplanet that fits the bill. Casey Newton is the daughter of a NASA engineer, and spends her free time sabotaging cranes being used to disassemble the Space Shuttle launch pad at Cape Canaveral.

Tomorrowland seems to have a fetish for space travel, which the film uses as a symbol for optimism and progress. Going further will require new insights and powerful new technologies. Right now, the best artificial intelligence systems in the world are finally conquering the problem of comprehending the literal meaning of text - a monumental undertaking. This echoes the difficulty of building artificial intelligence platforms that can interact with human beings in a way that feels genuine. As she puts it, "It's not personal - it's programming." Her inability to experience emotion or consciousness has lead to decades of bad blood with leading man George Clooney. One of the most interesting characters in the film is a recruiting android who ropes the protagonist into the plot. These aren't so far off from the humanoid robots already possible today, and they definitely reside in the uncanny valley.

Their skin, when it gets damaged, is clearly made of rubber, and you can see wires, motors, and microchips underneath. Unlike franchises like Battlestar Galactica and Blade Runner, which have embraced androids so humanoid that they hardly count, these androids are gratifyingly mechanical.
