Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

A bunch of US government accounts joined Bluesky last night, just before the No Kings rallies today. On Twitter, these accounts are known for using quote posts to direct their MAGA followers to harass people online. Use this list to block them all. Do not engage. Use “detach quote” if needed.

The Shire-Reckoning @shire-reckoning.bsky.social · 28d

The four Nazgûl pursuing Gandalf forsake the chase and turn back south. Three ride for the Last Bridge to prevent the Ring from crossing it.

The land is growing rocky, so Gandalf sends Shadowfax back to Rohan. The wizard sets out on an eleven-day hike through the Ettenmoors.

#booksky

Being clever enough to be a scientist is impressive enough on its own. Being able to explain science in a way that is approachable and entertaining is an entirely different skill (I’m talking Hawking, Nye, Sagan). But being able to to talk about science, and in doing so cause the reader to snort their coffee out of their nose in laughter is a skill reserved for a select few.

I read about this and had to try it myself. This is a screenshot of my phone after running the search “oreo spelled backwards” directly on Google. Check out the “AI” response.

When I was little, the U.S. military came to our home at gunpoint and took me and my family away. We were imprisoned for years in barbed wire camps simply because we were Japanese American. I have spent my life telling that story, hoping it would never be repeated.
