Self-Driving Car Update

"GM seeks US approval to deploy self-driving car without a steering wheel"

Cruise announced the filing of its petition for approval on Friday, saying the car is "a zero-emission, shared, electric vehicle that has been purposefully designed from the ground up to operate without a human driver. This means it does not rely on certain human-centered features, like a steering wheel or a sun visor, to operate safely."

Robotic Caterpillar

Video: "A caterpillar with nine electric motors climbs a woodpile!"

[T]he crux of the work was a gloriously fun math problem. Solving caterpillar motion over arbitrary curved surfaces is the toughest, and most rewarding, math that I’ve gotten into yet. It took me several months as well. The video is a single take, shot between 1:10pm and 1:20pm in my shop, when the sun aligns with a skylight to create a pool of light...

IEEE: "Their Bionic Eyes Are Now Obsolete and Unsupported"

Los Angeles–based Second Sight provides a cautionary tale for bold entrepreneurs interested in brain tech. What happens when cutting-edge implants fail, or simply fade away like yesterday’s flip phones and Betamax? Even worse, what if the companies behind them go bust?

Neuromorphic Analog Chips

"Chip designer mimicking brain, backed by Sam Altman, gets $25 mln funding":
Rain Neuromorphics Inc., a startup designing chips that mimic the way the brain works and aims to serve companies using artificial intelligence (AI) algorithms, said on Wednesday it raised $25 million.

 Gordon Wilson, CEO and co-founder of Rain, said that while most AI chips on the market today are digital, his company's technology is analogue. Digital chips read 1s and 0s while analogue chips can decipher incremental information such as sound waves.

Digital Dollars

NPR: "The U.S. is considering a radical rethinking of the dollar for today's digital world"

In that scenario, the U.S. would not only mint the coins and print paper bills. It would also issue digital cash, or a central bank digital currency (CBDC), that would be stored in apps or "digital wallets" on our smartphones.

We could then use them to pay for things, just like we do with Venmo or Apple Pay, and no actual physical money would change hands.
