As Alex notes in this thread, AI doesn't "democratize" science. Rather, it compels scientists to rely on anti-egalitarian means of directing their attention.

I know this'll ruffle feathers but I agree with this Food/Water watch analysis. Diverting renewable energy away from fossil phase-out and climate adaptation and towards melting graphics card to power chatbots is the formal end of moral purpose for clean technology.
Data Centers With Renewables Aren’t the Answer
So all these power plants and “temporary” turbines are raising power prices and polluting our communities. Why don’t we just power data centers with renewables?

Many data center companies are pledging to (eventually) do just that. But even if these pledges weren’t just empty greenwashing promises, powering data centers with clean energy is utterly unrealistic. It also threatens the progress of our already dangerously slow energy transition.

Continuously powering a 1 GW data center would require nearly 20,000 acres of solar panels or 185,000 acres of onshore wind power. We cannot afford to waste the time, space, or money to build renewables for Big Tech’s profit machines. 

Already, data center growth is outstripping available renewable energy supply and redirecting renewables from other industries. It’s drawing urgently needed renewables from existing technologies and resources. We need to focus our renewable energy resources toward thos

The Prime Minister of Spain: “This climate emergency is exceeding every threshold and scale that scientists have long warned all of Spain and Europe about.” This is the realistic climate discourse the world needs. www.nytimes.com/2026/07/28/w...
"These are difficult hours," Prime Minister Pedro Sánchez said
Monday afternoon during a news conference in Castellón, on Spain's eastern coast, where a new fire raged and forced thousands of new evacuations.
In the face of what his government has called the largest fires in the country's history, and after a summer of record-breaking heat waves, he called for a national pact with all Spain's political parties to work together to prevent blazes that he attributed to climate change.
"This climate emergency is exceeding every threshold and scale that scientists have long warned all of Spain and Europe about," he said.

The “vibe shift” proclaimed Nov. 2024 - Jan. 2025 was just some elites—in business, media, law, and some higher ed admins—who kinda liked the fascism and gave themselves permission to accommodate it. That’s all it ever was. A close presidential election is not somehow a binding cultural referendum.
