Watching tech people tremble before the awesome power of AI feels like when an actor is “attacked” by a wild animal in a movie but they are just holding a raccoon pelt to their neck and pretending to wrestle with it

the uncompromising nature of the vacation auto-responder when you are the only person who works here🌱
Thank you for your email! Casey/She's A Beast is on maternity leave until the end of 2026.

Unfortunately, she is the only one who works here, and owing to the demanding nature of taking care of a baby, her access to email will be intermittent at best. 

So regardless of the nature of your matter, I'm afraid you'll just have to wait.

I got into weights when I was pregnant and have continued it for the past 20-ish months after my daughter was born. I did not know I would fall in love with it. I started this book the other day and it’s been really interesting. Worth a read!

Jaysus Effin' Christ. I hope this leads to a better policy of scrutiny. www.nytimes.com/2026/01/06/b...
Editors’ Note: March 30, 2026:

A reader recently alerted The Times that this review included language and details similar to those in a review of the same book published in The Guardian. We spoke to the author of this piece, a freelancer reviewer, who told us he used an A.I. tool that incorporated material from the Guardian review into his draft, which he failed to identify and remove. His reliance on A.I. and his use of unattributed work by another writer are a clear violation of The Times’s standards. The reviewer said he had not used A.I. in his previous reviews for The Times, and we have found no issues in those pieces. The Guardian review of “Watching Over Her” can be read here.

What started as relief that RFK Jr. did not go shirtless this time quickly curdled into a creeping suspicion that something was deeply wrong. That the "pull-ups" we were witnessing were not, in fact, real. 🙏 to @caseyjohnston.bsky.social for the sharp, much-needed clarity

this writer learned about the Turners from my book, 'A Physical Education.' Fun fact about APE is that I can tell which reviewers actually read it based on whether they got to this part or not, and let me tell you a hell of a lot of them conclude "cute story of a little girl who learns to exercise"
