Right now generative AI has an “insatiable demand” for electricity to power the tens of thousands of compute clusters needed to operate large language models like OpenAI’s GPT-4, warned chief marketing officer Ami Badani of chip design firm Arm Holdings.

If generative AI is ever going to be able to run on every mobile device from a laptop and tablet to a smartphone, it will have to be able to scale without overwhelming the electricity grid at the same time.

“We won’t be able to continue the advancements of AI without addressing power,” Badani told the Fortune Brainstorm AI conference in London on Monday. “ChatGPT requires 15 times more energy than a traditional web search.”

Physicists have just found something no one expected, lurking on the surface of an arsenic crystal.

While undertaking a study of quantum topology – the wave-like behavior of particles combined with the mathematics of geometry – a team found a strange hybrid of two quantum states, each describing a different means of current.

“This finding was completely unexpected,” says physicist M. Zahid Hasan of Princeton University. “Nobody predicted it in theory before its observation.”

The extended mind — For decades, philosophers have debated the borders of personhood: where does our mind end, and the external world begin? On a simple level, you might assume that our minds rest within our brains and bodies. However, some philosophers have proposed that it’s more complicated than that.


When we merge mind and machine, the traditional borders of the self dissipate, says philosopher Dvija Mehta.
