Why Elon Musk and Other Geniuses Can’t Afford To Follow Rules

Mathematician Gregory Chaitin explains why Elon Musk is, perhaps unexpectedly, his hero

In last week’s podcast, “The Chaitin Interview III: The Changing Landscape for Mathematics,” Walter Bradley Center director Robert J. Marks interviewed mathematician and computer scientist Gregory Chaitin on many things mathematical, including why great books on math, advancing new theorems, aren’t written much any more. This week, we look at why geniuses like Musk (whose proposed Mars Orbiter is our featured image above) simply can’t just follow the rules, for better or worse: https://episodes.castos.com/mindmatters/Mind-Matters-126-Gregory-Chaitin.mp3 This portion begins at 7:57 min. A partial transcript, Show Notes, and Additional Resources follow. Gregory Chaitin: Look at Elon Musk (pictured). He’s my great hero. He’s a wonderful engineer and he’s a wonderful entrepreneur and he doesn’t follow the rules. Robert J. Marks: He doesn’t,…

Will a Brain-Computer Interface Be a Boon or a Nightmare?

BCI is probably coming anyway, and whether it is a good thing or a bad thing largely depends on how we choose to use it

Talk about a scary headline from an impressive research group!: “The Brain-Computer Interface is coming — and we are just so not ready for it” from the Bulletin of the Atomic Scientists. Okay, what’s going on? Both more and less than we think, depending on what we focus on. The Bulletin, published since 1947, is best known for a Doomsday Clock which expresses how close the editors think we are to nuclear war and climate apocalypse. An article in the current edition of the Bulletin covers the remarkable advances in prosthetics in recent years, in hooking up neurons (which use electrical signals) to electronic limbs, enabling much better control of prostheses. But the startling thing to realize is where researchers…

Paralyzed Subject Gains Control Much Faster via a New Technique

The earlier technique for controlling a cursor through brain-computer interface worked but it required constant relearning

Researchers at the University of California, San Francisco, have enabled a participant who is paralyzed in all four limbs to control a computer cursor, using only brain activity, by tapping into the brain’s own natural learning system. Without tapping into that system, brain-computer interface (BCI) needs extensive daily retraining in order to work. “It’s like asking someone to learn to ride a bike over and over again from scratch,” said study senior author Karunesh Ganguly, MD, PhD, an associate professor of in the UC San Francisco Department of Neurology. “Adapting an artificial learning system to work smoothly with the brain’s sophisticated long-term learning schemas is something that’s never been shown before in a paralyzed person.” Nicholas Weiler, “First ‘Plug and…
