Interview with Caprica's science advisor Malcolm MacIver

ScriptPhD.com has a really good interview with Malcolm MacIver, Caprica's technical script consultant, who sheds some light on the U-87 and the MCP. Here are some excerpts:

ScriptPhD.com: Your first Hollywood science experience involved consulting for a sequel of the 1980s cult classic Tron. What was it like to dive in from the Northwestern School of Engineering onto a set and work with screenwriters? What were some of your first impressions?

Malcolm MacIver: It was fascinating to learn a bit about how these huge expensive projects are structured. One specific thing I wanted to know more about was the role of writers in movies versus in TV. I had been told by friends in the industry that writers are typically less prominent players in movies than in top TV shows, were they can have considerable power. Consistent with this, we (the scientists who met with the Tron folks) were not introduced to the writers, who I believe were in the room taking notes, while we were introduced to all the other major players (director, producer, etc). I was also very curious to see how the group of scientists that I was a part of would interact with the movie makers. The culture gap is obviously huge, big enough for massive misunderstandings to blossom during superficially neutral discussions. During our meeting, our approach to the folks involved with the movie varied from inspired to less admirable attitudes. The less admirable attitudes seemed to arise from the mismatch between the importance scientists can place on their own endeavors, relative to their endeavor’s importance to story telling.

An anecdote I like along those lines is about how the astrophysicist Neil deGrasse Tyson complained to James Cameron that when Kate Winslet looked up from the deck of the Titanic, the stars in the sky were in the wrong position. I liked Cameron’s response, which was “Last I checked the film’s made a billion dollars.” People love the story, not the positions of the stars above the Titanic. We all tend to overemphasize the importance of the thing we are closest to, and it’s a problem that scientists need to be especially attuned to in these contexts.

SPhD: You are now a technical script consultant for Caprica, the television prequel to Battlestar Galactica, providing insight into things like artificial intelligence, robotics and neuroscience. To date, what has been one of your biggest contributions to a final written episode that otherwise wouldn’t have made it in to the storyline?

MM: One of the themes of my research is understanding the ways in which intelligence is not just all about what’s above your shoulders. Nervous systems evolved with the bodies they control—the interaction is extremely sophisticated, and stubbornly resists our attempts to understand it through basic science research or emulation in robotics. Representative of this fact is that we now have a computer that can beat the world chess champion—a paragon of an “above the shoulder” activity—while we are far from being able to robotically emulate the agility of a cockroach.

One of the things we’ve learned about the cleverness that resides outside the cranium is that things like the spinal cord are incredibly sophisticated “brains” operating sometimes without much input from upstairs. Through some old experiments that are better not gone into, scientists showed that animals can walk with little brain beyond the parts that regulate circulation and breathing and their spinal cord. This is because the spinal cord can do most of what we need for basic locomotion without any input. The point is that control of the body is distributed—it doesn’t just live in the brain. The lesson hasn’t been lost on robotics folks; for example, Rodney Brooks popularized an approach called “subsumption architecture” based on this idea. So – back to Caprica: For episode 2, “Rebirth,” the show needed some explanation for why the metacognitive processor was only working in one robot. The real reason, as we know, is that only one had Zoe in it; but the roboticists were being pressed by Daniel Graystone as to why it wasn’t working in others. The idea that I gave them, which they used, was that it was because this particular metacognitive processor had distributed its control to peripheral subunits. Because of this, it had become tied to one particular robot. It’s an idea straight out of contemporary neuroscience and efforts to emulate this in robotics.
