I hate to say it, but the colleagues positioning themselves to be pro AI in teaching and curriculum, are probably also positioning themselves to be administrators, and probably aren’t thinking about or don’t care how it will affect teaching, learning, or the careers of those around them.

It's a huge mistake to "adjust to" or "adapt" to generative AI. There's rarely been a more clearcut situation to reject vehemently for so many reasons. One reason beyond those that apply now is the future capacity for proactive manipulation and distortion. We need less outside interference not more.

Extremely normal and fine for a company to put this in a public statement
21. Some cultures have produced vital advances; others remain dysfunctional and regressive. All cultures are now equal. Criticism and value judgments are forbidden. Yet this new dogma glosses over the fact that certain cultures and indeed subcultures . . . have produced wonders. Others have proven middling, and worse, regressive and harmful.

22. We must resist the shallow temptation of a vacant and hollow pluralism. We, in America and more broadly the West, have for the past half century resisted defining national cultures in the name of inclusivity. But inclusion into what?

After revelations that companies like Ring have been selling home security footage to ICE, the most common defense of keeping a camera up seems to be, “But what if I’m stalked?” And as a violence researcher, I’m just here to state for the record that police do not care about your security footage.

As Trump holds Northwestern University hostage with $800 million in frozen funds, Northwestern leadership cracks down on students' right to free speech. These policies put more than 22,000 students at risk of punishment for peacefully protesting for any cause in any way.
Dear members of the Northwestern community,
With the new academic year upon us, we'd like to take a moment to reflect on the core of our mission - to create space for teaching and learning, where ideas flow freely, we learn from one another and push each other to create and discover.
This pursuit happens every day — all around us — in classrooms and labs, on stages and playing fields.
However, in our increasingly polarized world, at times we experience pain, confusion and challenging situations.
With that in mind, it's important to know the policies listed below that facilitate healthy dialogue, respectful disagreement and the exchange of ideas so that we can do our best work as students, faculty and staff.
We encourage everyone to take the time to read through these documents fully.
Demonstration Policy
The Demonstration Policy includes requirements and guidance on how, when and where members of the community may protest or otherwise engage in expressive activity. The policy prohibits overnight demonstrations and limits activity that disrupts classes and other functions of the University, including prohibiting demonstrations at the Rock before 3 p.m. on weekdays and the use of amplified sound in that area before 5 p.m.The Display and Solicitation Policy sets clear rules and requirements for on-campus displays, including flyers, banners, chalking and 3-D installations. The policy establishes designated areas for flyers, chalking and other displays and details when the University removes displays. This policy also prohibits the use of tents (with exceptions for University-sponsored events and for the purposes of guarding and painting the Rock), light displays and chalking on buildings. Signs that violate laws and other University policies are prohibited.

The Student Handbook, which contains the Student Code of Conduct (page 9), is updated each year. As a reminder, last year we made several policy changes, including:
- An Intimidation Standard that explicitly prohibits subjecting another person or group to abusive, demeaning, harassing, humiliating, intimidating, threatening or violent behavior that substantially affects the ability of the person or group to learn, work or live in the University environment. Examples of violations to this policy include physical threats, verbal or written communication to threaten violence, the use of symbols, words or graphics to threaten violence, acts of doxing, and abusive behavior toward a University official or agent acting in performance of their duties, among others. It also prohibits engaging in abusive, demeaning, harassing, humiliating, intimidating or threatening behavior that excludes a student from joining or participating in a student organization.
• The Failure to Comply Standard includes specific examples and to make clear that students are required to comply with the requests, directives and instructions of University officials acting in performance of their duties. Under this policy, students must identify themselves, including removing face masks or coverings for purposes of identification when asked by an authorized University official who is addressing law or policy violations and health or safety concerns.The Misuse of University Properties policy defines misuse, including unauthorized access to athletics fields and construction sites and attending or participating in an event in University spaces that violates the policies governing that space.
- The Destruction of Property Standard defines what applies under this policy to include tampering with University property.
Faculty and staff are encouraged to review their respective handbooks. Each member of the Northwestern community is expected to interact with each other with respect and consideration.
Additional Policies
In addition to the policies above, we want to remind you about the Office of Civil Rights and Title IX Compliance (OCR) policies concerning discrimination, harassment and sexual misconduct:
• Policy on Discrimination, Harassment, and Sexual Misconduct: This policy covers a wide range of discriminatory and harassing behaviors, including those based on race, ethnicity, religion, sex and other protected characteristics.
• Policy on Title IX Sexual Harassment: This policy specifically addresses sexual harassment and sexual misconduct consistent with Title IX.
• Reasonable Accommodation Policy: This policy explains the availability of accommodations for students, employees, job applicants, visitors and other third parties on the bases of disability, pregnancy, lactation and religion.
• Reporting by University Employees of Disclosures Related to Discrimination and Harassment: This policy sets out the reporting requirements for employees when they learn about discrimination, harassment and sexual
