They have made enormous headway. The central issue is that driving isn't _really_ a rule-based process; the rules are codifications of social mores but fundamentally driving around other people is about theory of mind and social negotiation, which ML is largely hopeless at; here's a thing I wrote.

The sequel to this story should be about those in civic institutions-partners at law firms, journalists & editors, university presidents & others-who simply have just gone along. The ease with which these figures chose collaboration is stunning & they should be held accountable for their actions.

It’s good to see papers start to address LLMs as structural plagiarism — provenance, more hidden than the original words or training data.

Alternative take: Universities (and all institutions really) are terrible at predicting job market changes over a timescale of 5 to 10 years. Thus, turning them into clout chasing vocational training centers is a stupid bet when the original Humboldtian mission showed surprising resilience.

This is one advantage of having the historical memory of authoritarianism, as I have from Brazil: you know that, when the regime is gone, the people who collaborated and acquiesced look terrible in retrospect. It may look reasonable and justifiable now, but believe me, it will age like milk.

The aim should be for individual, not institutional, accountability. Did a university obviously violate the first amendment rights of its faculty to suck up to Trump? Don't seek to fine the university, *seek to jail its president and trustees.* People make decisions, people bear consequences.

I really hate it when scientists keep saying that “we need to rebuild trust in science,” because it implies that scientists are to blame for the mistrust rather than the millions of dollars of dark money that have funded political attacks on science in order to advance a far right agenda.
