Ray Kurzweil and Marvin Minsky Discuss Artificial Intelligence, The Future of Work and Longevity, and other Aspects of the Singularity (Video) Review by: Guillermo Valle Pérez and Avi Roy In his discussion with Ray Kurzweil, Marvin Minsky proposes a top-down approach for trying to understand the mind, so that we focus on the patterns of thinking and then try to find which part of the brain does which function, instead of seeing how the smaller parts work and trying to find what patterns emerge. This is akin to saying that to understand how a computer works it’s more useful to understand its software rather than its hardware. His idea that, with the right models, we could program the high-level functions of human intelligence on a Pentium chip can be then understood by imagining how much less resources are needed to run the right recompiled version of a program than to emulate a whole machine to run the original version of the program. However, we think it likely that initial success will be achieved with the bottom-up approach. Prof. Minsky’s approach is the most natural, and indeed the only approach to understanding complex systems in the pre-supercomputer era. But with computers today capable of immensely complex simulations, we are starting to explain phenomena before we even understand it. Turbulence, for example, appears in our simulations of fluids following simple laws of physics, yet we don’t really understand why it happens. The same thing could happen with the brain in the next few decades, if estimates that exascale computing would be enough to simulate it at the neuron level are correct. During the discussion, Ray Kurzweil and Marvin Minsky also speculate about how increasing human longevity beyond 200 years, and the advent of true AI and of mind uploading will change the future of how we work and live.
