Today in the newsletter: X's final form, learnings from a packed week of earnings, and niche online Halloween costumes. Thank you for joining me. With the US election, X's transformation into Elon Musk's weapon reaches its peak. He has succeeded in bending his social network to his will. Last week, Musk deputized his followers to report any "potential instances of voter fraud and irregularities", tweeting about and linking to a forum within X called the "election integrity community".

A former interior minister, Tudorache is one of the most important players in European AI policy. He is one of the two lead negotiators of the AI Act in the European Parliament.

All systems are go for NASA's James Webb Space Telescope, which deployed its full gold-plated, sunflower-shaped mirror display Saturday. Now, the $10 billion successor to the Hubble telescope has five months of alignment and calibration procedures before it is expected to start sending images back to Earth, the space agency said Saturday. "Two weeks after launch, @NASAWebb has hit its next biggest milestone: the mirrors have completed deployment and the next-generation telescope has taken its final form," NASA announced Saturday. The news marked the completion of a "remarkable feat," said Gregory Robinson, NASA's Webb program director, in a statement. "The successful completion of all of the Webb Space Telescope's deployments is historic," he said.

To learn how actual news editors write headlines, Primer's system read more than 1 million news articles and the headlines they were paired with -- but only those where the headline was made up entirely of words found in the story. Once trained, it can read a new article and string together the best possible series of words to turn into a headline, according to Primer. In what Primer director of science John Bohannon calls a "headline Turing Test," evaluators were asked to rate computer-generated headlines against the originals -- without knowing which is which. In its final form, Primer tied or beat out humans more than half the time, the company said.
