On the *same day* the Cornell Seven drugged and raped Jane Doe, Cornell banned four students (including the President of Cornell JVP) from campus for three years for nonviolent, pro-Palestine protests. The same Cornell officials let the rapists off with apology essays.

Gone are the mass raids and militarized metro operations. Gone are the pomp and pageantry. But ICE arrests have hit record levels. ICE operations are no longer concentrated in large American cities. Immigration enforcement officials are also working in suburban and rural areas, all across the US.

Helping to power digital transformation
Australia is becoming a regional data centre hub, and a global leader for artificial intelligence (AI). We are helping to power digital transformation in the Asia Pacific and the adoption of artificial intelligence technologies scross broad sectors.

Our economy hosts an outsized AI industry, including over 1,100 private AI companies.
Adoption of AI is strong across society, with over 400 public firms developing or deploying AI solutions.
Our vibrant AI ecosystem and proximity to Asia means we are becoming a service provider for the region, with AI-related patents quadrupling over the past decade.
Sydney and Melbourne are both top-ten data centre markets in the Asia-Pacific region.
Australia’s abundance of renewable energy resources means we are a great location for regional, green data centres. This includes supplying Asia via subsea cables. 
Australia aims to become a global leader in developing and adopting trusted, secure and responsible artificial intelligence, led by the National Artificial Intelligence Centre.

When I left the Washington Post in 2023, my colleagues and I were worried AI would hoover up our work and enable "zombies" to churn out stories based on our reporting and writing styles. Today WaPo announced a partnership with OpenAI. And here it is: Zombie Gillian Brockell. I DID NOT WRITE THIS.
A screenshot of a ChatGPT conversation reading: "can you write something about robert e. lee in the voice of washington post staff writer gillian brockell?"
"Certainly! Here's an excerpt written in the voice of Gillian Brockell, a staff writer at The Washington Post, reflecting on Robert E. Lee's legacy: 

The Complicated Legacy of Robert E. Lee: A Figure Divided by History
By Gillian Brockell 
When Robert E. Lee's name is invoked, it is often as a symbol of Southern pride military brilliance, or a tragic, doomed cause. But history has a way of shifting its lens, and in recent years, the image of Lee -- the Confederate general, the hero of lost causes -- has become increasingly more fraught. The man who stood as the face of a rebellion that tore the nation apart now stands at the center of an ongoing reckoning over the Confederacy's legacy, and our struggle to reconcile memory with reality."
