“The most wealthy and powerful tech CEOs are still staying silent as ICE floods America’s streets, but now some researchers and engineers working for them have chosen to break rank.” Great @laurengoode.bsky.social story:

According to @unicef.org, women & girls spend 200 million hours per day collecting #water — robbing them of their time & their futures. Where #electricity is absent, running water often is too. SELF works to close this gap through solar-powered water systems. Learn more: www.self.org/water/

As usual, @rbreich.bsky.social is spot on the greed at the top. But is is only half the story. The depressingly accurate work by @gabrielzucman.bsky.social and Emmanuel Saez highlights how the ultra-rich now pay lower taxes than the poor. Society koyaanisqatsi www.nytimes.com/interactive/...

CEO pay is up 1,085% since 1978, while typical worker pay is up just 24%.  Why do we always hear "we can't afford to pay our workers more" but never "we can't afford to pay our CEO more"?

That is a key: the industry-regulatory bond is tight in @chinadigitaltimes.net - short-term benefit possible long-term concern? The related question is over cost dynamics: these are overnight costs and those of operation of young plants very different from later in life and of course at end of life

John Bistline@bistline.bsky.social

Interesting article in Nature suggests China has driven down nuclear power plant costs and kept them stable over two decades, beating the "cost escalation curse" with local supply chains and standardized designs. I wonder how much is transferable to other country contexts.
