Ponderings of science, philosophy, history, society, and many other topics
Spurred by a couple of recent conversations, I've been thinking about computation in the brain. It was accelerated this week by the news that the connectome of the fly brain is complete, a mapping of its 140,000 neurons and 55 million synapses. It's a big improvement over the 302 neurons of the C. Elegans worm, … Continue reading Classic and connectionist computationalism
In 1950, Alan Turing published a seminal paper on machine intelligence (which is available online). Turing ponders whether machines can think. However, he pretty much immediately abandons this initial question as hopelessly metaphysical and replaces it with another question that can be approached scientifically: can a machine ever convince us that it's thinking? Turing posits … Continue reading The problems with the Chinese room argument
The Scientist has an interesting article up reporting on the progress that's being made in neuromorphic hardware. But the fact that computers “think” very differently than our brains do actually gives them an advantage when it comes to tasks like number crunching, while making them decidedly primitive in other areas, such as understanding human speech … Continue reading Brain inspired hardware
A while back, I highlighted a TEDX talk by Anil Seth where he discussed that cognition is largely a prediction machine. Apparently Seth more recently gave another talk at the full TED conference, which is receiving rave reviews. Unfortunately, that talk doesn't appear to be online yet. But one article reviewing the talk focuses on something … Continue reading Why embodiment does not make mind copying impossible
Consider a rock outside somewhere. It sits there, starting off in the morning in a certain state. The sun comes out and proceeds to warm it up. Its temperature climbs through the day until the sun sets, whereupon it cools through the night. The cycle starts again the next morning. The rock is going through … Continue reading Are rocks conscious?
