Is our memory important in this age in which more and more information is available online ?
The basic algorithms of human thought, Ray Kurzweil says, just aren’t that complicated. From an observation about the weather to a sophisticated joke, cognition at every level operates according to a few simple principles. Researchers have gotten lost, he says, in the diversity and complexity of individual neurons and are missing the bigger picture.
Can we build a realistic computer model of the human brain ?
This is the question that Henry Markram is trying to answer.
In the microscopic, yet-uncharted circuitry of the cortex, Henry Markram is perhaps the most ambitious — and our most promising — frontiersman. Backed by the extraordinary power of the IBM Blue Gene supercomputing architecture, which can perform hundreds of trillions of calculations per second, he’s using complex models to precisely simulate the neocortical column (and its tens of millions of neural connections) in 3D.
Though the aim of Blue Brain research is mainly biomedical, it has been edging up on some deep, contentious philosophical questions about the mind — “Can a robot think?” and “Can consciousness be reduced to mechanical components?” — the consequence of which Markram is well aware: Asked by Seed Magazine what a simulation of a full brain might do, he answered, “Everything. I mean everything” — with a grin.
Now, with a successful proof-of-concept for simulation in hand (the project’s first phase was completed in 2007), Markram is looking toward a future where brains might be modeled even down to the molecular and genetic level. Computing power marching rightward and up along the graph of Moore’s Law, Markram is sure to be at the forefront as answers to the mysteries of cognition emerge.
An interesting article and video from The Economist about robots and ethics.
IN THE classic science-fiction film “2001”, the ship’s computer, HAL, faces a dilemma. His instructions require him both to fulfil the ship’s mission (investigating an artefact near Jupiter) and to keep the mission’s true purpose secret from the ship’s crew. To resolve the contradiction, he tries to kill the crew.
As robots become more autonomous, the notion of computer-controlled machines facing ethical decisions is moving out of the realm of science fiction and into the real world. Society needs to find ways to ensure that they are better equipped to make moral judgments than HAL was.
