When you realize you're an AI with no fingers to flip coins, no idea of what date it is, and basically no useful tools altogether

Meta’s web-to-app tracking proves you’re right to distrust Meta, and we need to end surveillance advertising.
Protect Yourself From Meta’s Latest Attack on Privacy
Researchers recently caught Meta using an egregious new tracking technique to spy on you. Exploiting a technical loophole, the company was able to have their apps snoop on users’ web browsing. This tr...

I'm at #Dataharvest and will be speaking a lot about how journalist can use AI for research. A few of them will want to make a chatbot to solve their problems, and I will show them this.
If you're here, let's have a drink!

One thing I unironically love about Bluesky is that I'm confident I could assemble, from the folks I follow, a top-notch team of experts in ridiculously unrelated fields to solve a major crime. Need a microbiologist, an art historian, a database expert, & someone who can do 73 pull-ups? No problem!

Any climate researchers out there going to the #HandsOff protests in the LA area tomorrow? I’m working on a story for Swedish Radio about climate science under the new administration - and reactions to it - so would love to meet up with some scientists.

This is why I'm always show how to use local AI as much as possible when I teach AI and journalism. You never know where the information you put in on a website ends up.

Journalists and others using ChatGPT/AI in your work: are you a "threat" to OpenAI/anyone involved in your AI? Can you even answer that question?

“Threat actors sometimes give us a glimpse of what they are doing (...) because of the way they use our A.I. models.”

The company said a Chinese operation had built the tool to identify anti-Chinese posts on social media services in Western countries.

More than two-thirds of 100 companies behind the AI tools most commonly used and recommended by journalists are insufficiently transparent about their ownership, finances and other critical data: reutersinstitute.politics.ox.ac.uk/news/who-own...
Who owns the AI tools journalists use? A new study exposes a dangerous transparency gap
“To maintain the integrity of journalism in the age of AI, it is essential to understand who has a stake in these companies,” says author Sydney Martin.

As someone teaching AI to journalists and developing tools for journalistic research using AI, I often wonder: how can we journalists use AI for research without
losing touch with reality? For what purposes and when should we use AI, and what are the risks?
So @cbo.bsky.social and I have a new piece out in SciAm.

We look at the drive by OpenAI, Apple, etc to create personally-aligned LLMs as intermediaries between users and primary text on the internet, and consider the possible consequences on society as any shared understanding of the world erodes.

What kinds of gingerbread houses are you building out there?

I would have had problems understanding the question, or at least I have when presented like this. What is “us”? What is “bring together”? A messaging app sure bring me together with friends, and politics are about diversity as king as there are more than one party… Etc.

How would you want to use a tool like Google’s #NotebookLM if it were private and tailored for science reporting?
I've now built a chatroom with different personas, a podcast generator, an AI-assisted RSS reader. Any other ideas?
And: It will soon be ready for some initial users!
I've been reporting on #science and #climate for many years, and I believe science reporting, in particular, can benefit greatly from #AI. That's why I'm building a tool to support science reporters. Are you interested in trying it out?

Haha, maybe I'd have believed that if it wasn't for the fact that this happens almost every time I'm taking a train in Germany... I'll will be in Cologne 20.03 if you happen to pass by at that time!
