Dreaming of a day an artist might create something like this for the waters beneath the ice of Enceladus and Europa; or even the surface of an oceanic exoplanet 🌊 (though in the latter case we'd be seeing wave expressions already thousands of years old)

When I was a kid I'd go hiking in the Sierras or eastern CA desert with my dad and there would be no sign of other people. I'd imagine that civilization had collapsed, inspired by the stale apocalyptic fiction of the late Cold War. That we'd come out from the backcountry and there'd be nobody left.

Girls are socialized to engage in self-doubt. Boys generally do not benefit from that containment mechanism for ignorant over-confidence. Once you see the dynamic, you cannot unsee it.

It feels like the US is running some kind of gonzo behavioral economics experiment. Like, what if we stripped unpopular but powerful climate policies of their climate connotations. Would they still work? Would they still be unpopular? Can we only the right things for the wrong reasons?

You know how everything bad gets blamed on video games & the internet? I have a theory that it’s golf destroying our society. Few activities have such an outsized effect on the environment, public health and epitomizing the corruption of wealth & privilege. Limit and restrict access to golf.

I have no idea if this is what's actually happening but it would be hilarious (as a housing activist) if all the resistance to data centers is ultimately revealed to just be garden-variety NIMBYism totally unrelated to instrumentalized "concerns" about AI, the broligarchy, or electricity prices.

This girl I used to waitress with in Austin, we moved to New York together in 2003 on a literal Greyhound bus. Shared a fifth floor walk-up studio that, when it rained, had more leaks in the ceiling than we had pots and pans. We used to get drunk and smoke off the fire escape and do “sad-offs.”

The situation is similar for soy. About half of all US soybean oil is used to produce fuel, not food. We could rewild close to half of the midwest just by switching from biofuel crops to solar + EVs. www.grainjournal.com/article/1058...

Underappreciated: US farmland *already substantially produces energy, not food*, and does so very inefficiently. Corn ethanol (~40% of all US corn) requires about 100 times more land per vehicle-mile driven than solar photovoltaics -> electric vehicles. Shifting corn to solar *would free up land*.

I have not seen much conversation about worker-owned AI models, nor have I seen any unions talking about collectively-owned platforms, but that's what a good alternative should look like. I do understand people will say that sounds insane; It usually takes about 7 years until people think I'm sane.

Whenever I'm forced to buy insurance I feel like I'm getting scammed. The sales department / agent will say anything to get you to pay the premium. And the claims department will do anything to avoid paying any money out. Like you need a whole separate legal team just to get a claim paid.
