Just two years after the world's first stored program ran its first program at Manchester in 1948, Alan Turing published his seminal paper “Computing machinery and intelligence". The paper opens with the words: “I propose to consider the question Can machines think?”. Turing then goes on to explore this question through what he calls the Imitation Game but which subsequent generations have simply called the Turing Test.

Despite spectacular progress in the performance and efficiency of machines since Turing's time, we have yet to see any convincing demonstration of a machine that can pass his test. This would have surprised Turing - he believed that all that would be required was more memory. Although cognitive systems are beginning to display impressive environmental awareness, they do not come close to the sort of "thinking" that Turing had in mind.

Prof Furber argues that our problems with true artificial intelligence lie in that we have yet to really understand what natural intelligence is. Until we do, all discussion of machine intelligence and "singularity" are specious. Based on this view, we need to return to the source of natural intelligence, the human brain.

The SpiNNaker project has been fifteen years in conception and eight years in construction, but is now ready to contribute to the growing global community (exemplified by the EU Human Brain Project) aiming to deploy the vast computing resources now available to accelerate our understanding of the brain, the ultimate goal being to understand the information-processing principles at work in natural intelligence.

More about Prof Steve Furber

Steve Furber is ICL Professor of Computer Engineering in the School of Computer Science at the University of Manchester. After completing a BA in mathematics and a PhD in aerodynamics at the University of Cambridge, he spent the 1980s at Acorn Computers where he was a principal designer of the BBC Microcomputer and the ARM 32-bit RISC microprocessor.

Over fifty billion variants of the ARM processor have since been manufactured, powering much of the world's mobile and embedded computing. He moved to the ICL Chair at Manchester in 1990. He has led research into asynchronous and low-power systems and, more recently, neural-systems engineering, where the SpiNNaker project is delivering a computer incorporating a million ARM processors optimised for brain-modelling applications.
