Claude-generated graphs of the estimated ideology of the median Supreme Court justice and presidential vote shares. Obviously not causal; intended to illustrate the discrepancy between public opinion and the Court.

"Despite the Court’s admonitions not to 'get to a point where someone is telling me, from the govt., that it’s too late, too many things have happened and now we are, like, moving forward and we can’t, you know, stop the trains'" Defendants have begun irreversible damage to East Potomac Golf Course"

Their defense is that the acceptance rate is just over 50%! For what used to be an extremely selective position.

Just got my first AI slop paper to review & am totally ripshit per @novosad.bsky.social - what a waste of time! AI is amazing but can destroy science while revolutionizing it. Editors: We are looking for journal partners to study how to use AI to make scientific publishing better (not worse). LMK!

Open racism by the Republican nominee for an important statewide office in TX (regulates oil and gas). What's especially tragic is this picture shows the magic and genius of America.

Both can be true at the same time: 1. AI progress is still exponential and people who dismissed it were wrong; disruptions will grow 2. 10-15% growth rates and/or extinction-level events* remain highly improbable To be clear, the harms could still be tremendous and we should try to prevent them!
