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.

I'm not saying this is a good thing but if I'm reading a novel and come upon a big chunk of poetry or song lyrics, maybe written by the protagonist maybe even crucial to the plot, the only thing I think is: cool I can skip this page

The actual health obstacles that face us at this point are food access (quality, price, content) and movement access (ability to go anywhere without involving a car). Not only are we not fixing them, the govt is tripling down on making the problems worse, WHILE telling us, you gotta eat healthier!

We’ve lost all concept of this, but government services are not supposed to be profit making enterprises. government services are not publicly traded corporations. They are, and I can’t stress this enough, government services
