Scoop: Trump flew secretly from Turkey on an alternate military aircraft unbeknownst to journalists and some White House staff members who believed they were on the same plane as the president, The Post has learned. w/ @DanLamothe @abtran & @joyceslee https://t.co/CZqvHnfi44

I bought a detailed list of wealthy, suburban New Yorkers who smoke cigarettes. It took a credit card. Nobody on the list agreed to be on it, and buying it was legal.

Exact Data's portal lets advertisers build lists on hundreds of factors.
There are hundreds of brokers like them, and whether you can force them to delete you depends entirely on which state you live in.

I dug into a Russian influence op that uses video games and social media to lure young people to work in a drone factory. For @StraightArrow__

A custom-tailored list of wealthy New York suburbanites who smoke cigs can be yours — with little more than a credit card.

My latest deep-dive offers an inside look at the shady world of data brokers that power targeted ads.

My new investigation is the first comprehensive look at how a mass shooter used ChatGPT. There are some big questions about the role of artificial intelligence here, and OpenAI is not answering them https://t.co/A8PgV9HS2i

“Non-invasively … read … the … human … mind”

[Naomi Bashkansky @NaomiBashkansky]

Two weeks ago, I resigned from OpenAI to join Conduit as a founding researcher, where we're training models to non-invasively read the human mind.

I've written some thoughts about what telepathy could look like by 2035 and how to get there:

No First Amendment for prison journalists

The law has constructed a regime in which incarcerated journalists are silenced and punished for telling the truth about what happens behind these walls.

FWIW, I wrote a story earlier this year about how ICE was tapping the help of local police officers to search Flock cameras on K-12 school campuses. The searches had nothing to do with kidnappings or theft. @TheFP https://t.co/VjQorZtP1H

[Mark Keierleber @mkeierleber]

Pretty interesting to see how investigative journalism has led to the swift public backlash of Flock's surveillance practices in the last few months. (Recent example: https://t.co/4FXw0DeH1r)

The Free Press comes to the story with a very different conclusion.

[The Free Press @TheFP]

Ever feel like you're being watched? You might be right.

But Flock Safety cameras aren't interested in you—unless you're a kidnapper, a thief, or up to no good.

How much of the decline in media trust is actually about the media’s actions, versus the narratives that get spun about them? https://t.co/CWr7hXm52r

Ladies and gentlemen, it's time to pass the torch and demote myself to my natural state: a poster. I'll be stepping back from leading product for 𝕏 and will continue on as an advisor.

Serving the X community has been the privilege of a lifetime. X is, and will remain, the most important communication technology in history. But running this app is a 24/7 job and it's now time for me to take a breather.

The app is seeing unprecedented growth in new users & engagement. We continue to break records every month. We've climbed 70 spots in the App Store since this time last year.

And in the last 400 days, we rebuilt almost every aspect of X: the Timeline, the Android app, onboarding, notifications, chat and more.

We also launched nearly 30 new products while protecting the integrity of the town square: becoming the first app to show Country-of-Origin on profiles and mounting defenses against AI bots. There's certainly much more work to be done, but our foundation is stronger than ever.

None of this would have been possible without the incredible team here. The next leaders will take X to even greater heights with @benjitaylor on design, @singhai on core product engineering and @dinkin_flickaa on mobile engineering -- among many other great people.

Thank you to Elon and the X team for welcoming me into the company. See you on the Timeline.

Social media make you feel like hot garbage? Ya, me too.

But don’t blame the algorithm, according to these Virginia Tech researchers. Blame yourself.
