What’s Driving the Turnover at Musk’s AI Startup?

gizmodo.com Lucas Ropek 2025-09-23 10:50:37

Elon Musk’s xAI has lost a large number of top executives in recent months—so many that onlookers have begun to wonder what’s causing the high turnover rate. Now, new reporting from the Wall Street Journal suggests some of those executives may have left due to internal conflict over the management style at the company and disagreements over its financial projections. The list of executives who have recently departed Musk’s firm includes Mike Liberatore, the company’s former chief financial offi

Algebraic Types are not Scary, Actually Posted on 2025-08-30 You may have heard the term algebraic types before, which initially sounds like an advanced concept, that only someone with a PhD in programming languages can understand. Quite the contrary, algebraic types is a very simple and helpful concept about programming in general. Anyone who knows basic algebra could understand what algebraic types are. In this article I aim to provide an explanation of algebraic types for the working progra

Axial twist theory

Scientific theory in vertebrate development Axial twist Schema of the proposed development of the axial twist. Developmental phases are (from top to bottom): (1) the embryo turns on its left side; (2) the anterior head grows in the same direction, but the rest of the body grows oppositely into a twist. So that ultimately (3) external bilateral symmetry is regained. Note that there is no evolutionary pressure for internal symmetry so the heart (and other organs) remain asymmetric. Details System

xAI’s CFO is the latest executive to leave Elon Musk’s AI firm

techcrunch.com Rebecca Bellan 2025-10-18 10:27:06

In Brief Mike Liberatore, xAI’s chief financial officer, has left the company, according to reporting from The Wall Street Journal. This marks the latest in a string of high-profile executive departures. The former Airbnb executive joined the company in April and left around the end of July, per WSJ.

Does this site show that AIs are biased? As of 2023, every major AI is economically left-wing and also relatively socially libertarian. Some AIs are much more like that than others, however, with Claude tending towards being one of the most moderate models, and Google’s Bard being one of the most extreme-left models.

This Week’s ‘Star Trek: Strange New Worlds’ Hid a ‘Doctor Who’ Easter Egg in Plain Sight

gizmodo.com Justin Carter 2025-11-18 06:50:15

The latest episode of Star Trek: Strange New Worlds planted the seeds for what’ll eventually become classic Star Trek by giving James Kirk (Paul Wesley) time in the captain’s chair. Along the way, it also decided to have a little crossover with Doctor Who. In this week’s “The Sehlat Who Ate Its Tail,” Kirk and the Farragut crew have to rescue the Enterprise from the tendrils of a power-draining scavenger ship.

How to configure X11 in a simple way

Speaking about xrandr . I tried some GUI applications, like arandr, to switch between various multimonitor configurations — but found that they all are using just a limited subset of xrandr features. For example, I can't use mixed DPI settings or scale some outputs with arandr, but I can do it with xrandr: https://mas.to/@evgandr/114394277310057344. Yes, the X can do that!

The surprising geography of American left-handedness (2015)

A pre-K teacher in Oklahoma is making news this week after forcing a left-handed 4-year-old boy to write with his right hand. The boy was sent home from school with an article discussing left- and right-handedness. The article mentions historic attitudes toward left-handedness that associate it with evil and the devil. It's written carelessly enough that it isn't clear whether the writer believes left-handedness is still seen as evil or whether that was only the case in the past. Regardless, it

Elon Says He’s Working to ‘Fix’ Grok After AI Disagrees With Him on Right-Wing Violence

Billionaire conspiracy theorist Elon Musk really doesn’t like it when Grok says anything that contradicts his far-right worldview. And that’s exactly what his AI chatbot did late Tuesday when an X user asked whether people on the political right or the political left have been more violent since President Donald Trump was first elected in 2016. Grok said it was people on the right. Musk responded that he was working to fix Grok so it wouldn’t do that again. It all started on Tuesday in a tweet
