Trump’s Humiliation in Orbán Defeat Stunner Is Only Just Beginning For Viktor Orbán’s epic loss in Hungary to have real meaning in America, Democrats and liberals need to proclaim themselves part of the global anti-authoritarian movement.

The massive Orban defeat should prompt Dems to align themselves more firmly with anti-fascist and pro-democracy forces abroad. There's a powerful link to be drawn between the celebrations in Budapest and the confrontations with ICE in Minneapolis. 1/

True. History can be inconvenient to the performatively patriotic. Love your country through the lens of truth, not idealization. AIM toward a better future, but don’t LIE about past mistakes.

America BADLY needs an AA meeting.

A ghostly view of the Sun's corona seen from behind the Moon, portions of which are faintly visible from Earthshine (our planet is off screen to the left). At lower left, the bright point of light is Venus.

This is haunting.

More from yesterday's solar eclipse viewed by the Artemis II crew.

The Sun's corona is faintly visible emerging from behind the Moon.

And, at lower left, Venus.

The President of the United States is threatening to commit war crimes and wipe out a "whole civilization" — all because he started a disastrous war of his own making and had no plan and no strategy for how to end it.

This is abhorrent, and the American people do not support this.

Today’s surreal split screen: Brave, brilliant astronauts swinging AROUND THE MOON, returning wondrous new photos of our exquisite planet and its ancient companion, while our dangerously unhinged “leader” threatens unspeakable war crimes.

Searching for those missing pieces of our origin story that are waiting for us up there…

I did a thing in Today’s NYTimes.

NASA isn't why the US doesn't have universal healthcare, or a social safety net. The US doesn't have those things because politicians with the power to provide them choose specifically not to (with varying levels of support from voters). Enthusiasm for human spaceflight doesn't drive that choice.

Thoughtful discussion by @drfunkyspoon.bsky.social and @nvpatel.bsky.social on the risks and benefits of going to the moon. To me, one of the most exciting prospects is finding 3 and 4 byo Earth rocks up there, perhaps right where they landed after the Really Big One.

This is super-cool: complex life in the Ediacaran!
Also, I saw a tufted sausage doing a pirouette just the other day. What are the chances?

The task of writing in the age of AI is the same as it has always been: to see through the various manias and cults, to unpack the mechanisms that make the world turn, to ring the bells that still can ring.

Common sense might also help. “Render unto man the things which are man’s and unto the computer the things which are the computer’s,” Norbert Wiener, the father of cybernetics, wrote. “This would seem the intelligent policy to adopt when we employ men and computers together in common undertakings. It is a policy as far removed from that of the gadget worshiper as it is from the man who sees only blasphemy and degradation of man in the use of any mechanical adjuvants whatever to thoughts.”

Huh. Here’s a piece about using AI for writing that is actually interesting and provocative. Neither fawning nor reflexively fearful.
