Last term I tried an experiment: I walked into my Tech and Design Ethics class, admitted that I had *no idea* what to do about ChatGPT - so I would let them figure it out.

On tonight's All Things Considered on NPR, I discuss patients' use of AI for health. While there are risks, many patients benefit.
Overall, I favor tools that guide patients through their symptoms (with iterative Q's & A's) rather than general tools like GPT or Gemini.

I'm a surgeon – and I've been shot. ICE denying Renee Good aid is inhumane.
I do not know if Renee Nicole Good could have been saved; no one can say with certainty. But she should have been given every possible chance.

I’m seeing a ton of disinformation from the right wing about California’s new law requiring folic acid fortification for corn masa flour, so here are some facts (US only).
1. By law, wheat flour has been fortified with folic acid since 1998 to prevent neural tube defects like spina bifida.
