Surrogates. Not a great movie* but thought provoking in a possible-robot-futures kind of way. The first thing that made it interesting was that the imagined robotic technology doesn't rely on Artificial Intelligence (AI), unlike most robot sci-fi. In that sense, therefore, its fictional future is rather more plausible than most robot movies, although still very challenging. In the Surrogates future humans put on some kind of headset that enables them to see through their robot's cameras, hear through its microphones and (presumably) smell through its olfactory sensors. This is a Brain-Computer Interface (BCI); there are two kinds of BCI, non-invasive - as in this movie, or invasive (the Matrix).
For me, however, the most interesting question raised by the movie is this. If you had the opportunity to live your life through a beautiful robot proxy, so that you see, hear and touch the world not directly but through its senses, and you interact with (most) other people even more indirectly, via their surrogates, would you..? Not just occasionally, for fun, but 24-7 - work and play. Would the experience be so compelling, so addictive, that it justifies spending your days lying prone on a couch jacked into an immersive real-reality, emerging only to pee and eat pizza (delivered presumable by surrogates)? Would social pressures or fashion compel you to surrogate-up, otherwise as a real human - lumpy and unattractive (not you dear reader) - you find yourself in a world of super-model surrogates?
*Although I thoroughly enjoyed it. The plot is thin and predictable but Bruce Willis and his wife (played by Rosamund Pike) are excellent. And the makeup of the human-actors-playing-surrogates provoked in me a not-quite-out-of-the Uncanny Valley response, that really held my attention.
