Happy Friday, Chicago.

This Christmas, I want a new bookshelf so I finally have somewhere to put the piles of books I have yet to read. Maybe I’ll have a little leftover after I pay my property taxes, the subject of one of today’s editorials — and of much ire across Cook County this holiday season.

Our second editorial covers an absurd suggestion from Chicago Treasurer Melissa Conyears-Ervin (who also happens to be running for Congress): She wants to “boycott” investing in securities issued by the United States Treasury as a protest against President Donald Trump, a foolish stunt that puts everyone at risk.

On the opinion page, columnist Elizabeth Shackelford paints a haunting picture of genocide in Sudan with such evocative prose it’ll stick with you long after you finish reading.

We also have plenty of fascinating content from the medical perspective. Retired Dr. Cory Franklin ponders what AI means for the future of health care, including convenience and efficiency for patients but more complicated prospects for physicians, some of whom AI may make obsolete — and privacy risks for all.

Dr. Robert Redfield urges a swift and unified response to the Alzheimer’s crisis playing out here in the U.S., as the country’s 7 million Alzheimer’s cases are expected to double by 2050.

Don’t forget to check out our reader letters (and keep ’em coming).
