Really interesting. Looking forward to dice deeper. Especially thinking, oh as a vegetarian i‘ll probably be well on track and realising that dairy overconsumption is HUGE in Europe
Thinking of European Commission staff behind the Farm to Fork Strategy when they'll read the new #EATLancet report.... They had it all right, and it's a real shame the EU's blueprint for healthy, fair and environmentally friendly #FoodSystems was derailed.

On the overwhelming public support for climate action: Great to see Ximeng Fang and Stefania Innocenti quoted on their research that sparked the 89% Project. (And globally, 69% of people are willing to give 1% of their income to help fix climate change.) @coveringclimatenow.org

Full service AI. Not only did it identify the targets and write the code to hack them... it also suggested how much to try to extort them for and even helpfully wrote the ransom notes.
Anthropic says a hacker used its Claude chatbot "to an unprecedented degree": Claude identified vulnerable companies, wrote infostealer malware, analyzed stolen files for extortion purposes, calculated extortion amounts, and wrote extortion messages. www.nbcnews.com/tech/securit...

Remember, when Barcelona eliminated 3 lanes of vehicle traffic & converted this street into a 4.7km green pedestrian corridor in the heart of the Eixample grid, businesses sued. They actually won. But by decision-time, the businesses had decided they actually like it.

Put another way: if you can supervise it effectively enough to catch its mistakes, you probably didn't need it in the first place.
