Leavitt: "I think it's frankly ridiculous that anyone in this room would even suggest that President Trump is doing anything for his own benefit. He left a life of luxury and a life of running a very successful real estate empire for public service."

Trump: "We already made a great deal. We're not doing business with China right now. We lost $1 trillion with China last year, so if you're not gonna do business with them, you're not gonna lose $1 trillion."

I’m sorry but if your students use AI to write papers and you use AI to grade them zero school is happening. You are running together on a hamster wheel
Why even have a brain, any ideas, any ability to express them, any kind of communication with other people, any desire to solve problems or invent anything, any reason to learn, any use for your eyes or your heart, or any reason to teach or create

Even accepting the premise that AI produces useful writing (which no one should), using AI in education is like using a forklift at the gym. The weights do not actually need to be moved from place to place. That is not the work. The work is what happens within you.

This isn't even close to what America has lost. It is alone. No friends. Nobody will ever trust it again. Every interaction with other countries will be transactional. There is no goodwill. You will pay and pay and pay and we will all be poorer.
This is painful, and saddening, and embarrassing. I feel like we're losing a member of the family - and for no good reason other than that some Americans wanted another season of the worst reality TV show in history.
