Today in life under competitive authoritarianism

A $30 million "fine" for no crime. Politically-motivated extortion of private institutions.
Breaking News: Cornell University reached an agreement with the Trump administration that would restore hundreds of millions in funding to the university. It's expected to pay a $30 million fine to the government and to invest $30 million in agriculture and farming programs.
Cornell Reaches Deal with Trump Administration to Restore Research Funds
The Ivy League university had warned of layoffs after the Trump administration stripped it of funds this year. The cuts were among the deepest in higher education.

This is due to being overwhelmed by a hundreds of AI generated papers a month.

The UC Regents finally released the “settlement agreement” the Trump administration proposed in August. It’s a doozy.

UC alumni, faculty, staff, students, parents, donors—and all citizens of California:

Now is the time to let the UC Regents know you do not want them to sign this bad deal.

A university that signs the “compact” is one that acknowledges its own inability to compete and succeed based talent and merit. It would signal insecurity and mediocrity to current and future students and faculty. Say no. Recruit the best people, protect their freedom and support their hard work.
