Tonight, on behalf of Minnesota law enforcement, I filed a lawsuit against DHS to prevent the destruction of evidence related to the fatal shooting of Alex Pretti.
DHS is not above the law, and Alex sure as hell is not beneath it.

I just created a series of seven deep-dive videos about AI, which I've posted to youtube and now here. 😊
Targeted to laypeople, they explore how LLMs work, what they can do, and what impacts they have on learning, well-being, disinformation, the workplace, the economy, and the environment.

This might be the first time I’ve seen someone present the base rates while directly ignoring them.
White House Deputy Press Secretary seen here posting data showing how much more prevalent right wing domestic terrorism is than left wing domestic terrorism... while thinking she's showing the reverse.
Apparently she can only read headlines, but not the actual graph with the data.
