A thing I really wish mainstream media would understand about AGI is that it's a play by post for absolute dweebs. If someone is talking to you about what AGI will do to/for humanity: that is a dweeb telling you about their GURPS campaign. It isn't news because it isn't real.

Reading my bookshelves: The Squirrel on the Train by Kevin Hearne and North Continent Ribbon by Ursula Whitcher. Two novella-length books, one is a fun fantasy mystery with a dog point of view, and the other is a set of loosely linked science fiction stories that are just brilliant.

Sharing this now because The Redemption Center Is Closed On Sundays drops May 26. Feels right to look back before the next chapter lands.

It's VERY important to understand what's happening with the NASA 🔠budget. White House proposed cuts to everything *but* Artemis. The GOP-led House proposal restores the size of the budget BUT shifts spending, which is to say *House committee and White House agree on cutting NASA astrophysics* 🧪⚛️

Recently, FamilySearch digitized and uploaded tons of microfilmed records, including many from 18th-century Massachsuetts. They're using some sort of AI to transcribe/summarize the handwritten documents. I've noticed that the AI strips out references to race and enslavement in 18thc documents.

Kinda tired of the "historians will say they're close friends" meme. Babe, we've been screaming about how gay everyone is for *decades*. Funding for history keeps getting cut as a result. There are entire moral panics about it. You just haven't read any history since highschool.
