The crash is going to be brutal when it comes.

Robinhood says "it might offer "tokenized" equity in OpenAI. By "tokenized," Business Insider reports, Robinhood means "blockchain-enabled representations of securities like stocks." In reality, they have no connection to OpenAI equity whatsoever."

Growth = minimizing the number of people who are hungry, sick, homeless, or not free, within planetary constraints.

It's not complicated (in principle).

Aarne Granlund @aarnegranlund.bsky.social · 2d

”For sustained growth, governments often reach for tried-and-tested ideas, such as loosening regulations to build more roads or expand airports — giving less thought as to whether that growth is inclusive or undermines sustainability goals”

Some of the white pines, symbols of peace, that are around my house located on the traditional land of the Gayogo̱hó꞉nǫʼ may have been here in the 1820s when Erie canal was built and the Haudenosaunee were cheated out of their lands, displaced, and largely decimated.

Far as I can tell, Robert Redford was:
* successful at everything he tried
* genuinely intelligent & insightful
* desired by women
* envied by men
* an absolute mensch to everyone he dealt with
* a tireless, lifelong philanthropist
... and he died peacefully in his sleep.

10/10 life. No notes.

Despite all the noises off, most big corporates are still increasing investment in sustainability, because climate risks and real and clean tech is competitive. www.businessgreen.com/news-analysi...

Why reports of the demise of corporate climate action have been greatly exaggerated

Global survey of corporate executives shows capital investment in sustainability and climate risk efforts is increasing - and so are the financial returns

Global business should be all over climate change, particularly the financial sector. Risk management is their core.

Climate change is very bad for business and their economic analysts see the writing very clearly on the wall.

Why are the Nordics happier and healthier than most countries? Lower inequality. It's costly but generates huge benefits for all.

Aarne Granlund @aarnegranlund.bsky.social · Sep 10

(Which eventually results from unregulated capitalism and socio-economic inequality)

Status competition leads to social dominance hierarchies and conspicuous consumption.

There are always alternatives.
