The Portland Frog army has now infiltrated Tulsa, OK and they’ve made an unlikely alliance with the T-Rex infantry and Sharks on Hoverboards mercenary forces.

This is truly terrifying.

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).

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.

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.
